[0024] Next, the embodiments of this specification are described in detail.

[0025] The following combination Figure 1 The system architecture of the redirection method and apparatus for USB multi-mode devices in the embodiments of this specification is described. It should be noted that: Figure 1 What is shown is merely an example of a system architecture to which the embodiments of this specification can be applied, to help those skilled in the art understand the technical content of this specification, but it does not mean that the embodiments of this specification cannot be used in other devices, systems, environments or scenarios.

[0026] Figure 1 It is a schematic diagram of a system architecture shown in this specification according to an exemplary embodiment.

[0027] like Figure 1 As shown, the system architecture may include, for example, a terminal device, a network and a server. The network is used to provide a medium for a communication link between the terminal device and the server. The network may include various connection types, such as wired and / or wireless communication links, etc.

[0028] Users can use terminal devices to interact with servers through the network to receive or send messages, etc. Various communication client applications can be installed on the terminal devices, such as service access clients, web browser applications, search applications, instant messaging tools, email clients and / or social platform software.

[0029] The terminal device can be various electronic devices with a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop portable computers and desktop computers, etc. The terminal device can be connected to a USB multimode device, which refers to a USB device that can be operated in multiple modes or uses. After being connected to a computer or host, this type of device can change its device mode as needed. For example, a USB multimode device can include a USB wireless network card, a USB printer, a USB camera, etc. with multiple modes.

[0030] The server can be a server that provides cloud desktop services. Cloud desktop services are a desktop virtualization solution based on cloud computing technology, which allows users to access a virtualized desktop environment through the Internet. This service provides a centrally managed, scalable, on-demand computing environment, and users can remotely access the server from a terminal device to obtain cloud desktop services.

[0031] In the cloud desktop scenario, the following problem exists: the cloud desktop cannot correctly identify the device mode of the USB multi-mode device when the USB multi-mode device switches modes. After the driver is installed in the cloud desktop, the USB multi-mode device is always in the initial device mode and cannot be switched to other device modes.

[0032] Take a multi-mode printer as an example. When a multi-mode printer device is inserted into a terminal, the initial mode is a USB storage device. The operating system of the terminal broadcasts a device insertion event, which is detected by the USB redirection service. After the USB redirection service finds that a new USB device has been inserted, it is ready to redirect it to the cloud desktop. But first, the driver of this device needs to be replaced with a USB redirection driver. The reason for replacing the USB redirection driver is that it is necessary to take over the control of this USB device so that other programs in the operating system cannot use this USB device. The driver replacement process requires resetting the multi-mode printer device. During the reset process, the multi-mode printer device is first ejected and then inserted. After reinsertion, the multi-mode printer is still a USB storage device type. The USB filter driver of the terminal kernel loads the USB redirection driver for the multi-mode printer device object. When the USB redirection service detects that the device has completed loading the USB redirection driver, it can initiate USB redirection and share the multi-mode printer to the cloud desktop.

[0033] According to the normal USB redirection process, a virtual USB device object is created in the cloud desktop. Then the cloud desktop operating system loads the USB storage driver for the virtual device according to the device classification "USB storage" and displays it as a storage device. At this time, if the driver of this multi-mode printer has not been installed in the cloud desktop, you need to install the driver manually. After the installation is complete, the kernel loads the multi-mode printer driver. The multi-mode printer driver will send a mode switching instruction to the virtual USB device object to switch the printer device to USB printer mode.

[0034] After receiving the command to switch modes, the multi-mode printer of the terminal will reset to switch from USB storage mode to USB printer mode. During this reset process, the multi-mode printer device will be ejected and then inserted from the terminal operating system. The USB redirection service of the terminal listens to the device ejection event and unredirects the device from the virtual machine. Then, the multi-mode device is reinserted into the terminal. At this time, the multi-mode printer is already in printer mode. The USB redirection service of the terminal listens to the device insertion event and prepares to redirect the device to the cloud desktop. It sends a command to reset the device to the multi-mode printer again to replace the driver with the USB redirection driver. The multi-mode device is reset again, and after being ejected and reinserted, its working mode returns to the initial USB storage device mode. The terminal operating system loads the USB redirection driver for the multi-mode device. The USB redirection service detects that the USB redirection driver has been loaded for the multi-mode printer and redirects the device to the cloud desktop.

[0035] After the multi-mode printer is redirected to the cloud desktop again, because it is in USB storage device mode, the corresponding virtual device in the cloud desktop is also in storage device mode. The cloud desktop operating system loads the USB storage driver for the virtual device according to the device classification, and the multi-mode printer is still a storage device in the cloud desktop. Therefore, this device is always identified as a USB storage device in the cloud desktop and cannot be used normally.

[0036] The following is a detailed description of the redirection method for a USB multi-mode device provided in the embodiments of this specification. Figure 2 As shown, Figure 2 This is a flowchart of a method for redirecting a USB multi-mode device according to an exemplary embodiment of this specification. The method can be applied to a terminal device, and the terminal device can be connected to a USB multi-mode device via USB. The method for redirecting a USB multi-mode device provided in the embodiment of this specification may include the following steps.

[0037] In step 210, device information of the USB multi-mode device is obtained, and the USB multi-mode device is in the first mode.

[0038] In step 220, if the device information matches the preset USB driver replacement policy, the USB redirection driver is loaded.

[0039] In step 230, the USB multi-mode device in the first mode is redirected to the cloud desktop using a USB redirection driver.

[0040] In step 240, after the USB multi-mode device is switched from the first mode to the second mode, the USB multi-mode device in the second mode is redirected to the cloud desktop using a USB redirection driver.

[0041] According to the embodiments of the present specification, the USB redirection driver is automatically loaded according to the USB driver replacement strategy, and the USB redirection driver takes over the driver of the USB multi-mode device in the terminal operating system, thereby redirecting the device to the cloud desktop. This can solve the problem that the user cannot correctly identify the device type mode of the USB multi-mode device in the cloud desktop, so that the user can use the USB multi-mode device normally in the cloud desktop.

[0042] According to an embodiment of the present specification, a USB multi-mode device may be a USB device with multiple modes, such as a USB wireless network card with built-in driver software, a USB printer, a USB camera, etc. Exemplarily, in the present embodiment, a USB multi-mode device may include a first mode and a second mode. The first mode may, for example, be the initial device mode of the USB multi-mode device. The second mode may, for example, be the device mode corresponding to the target function of the USB multi-mode device. For example, for a multi-mode USB printer, the first mode may be a USB memory mode, and the second mode may be a USB printer mode. In the USB memory mode, the USB printer is identified as a USB memory and can be used to provide a device driver. In the USB printer mode, the USB printer is identified as a USB printer and can be used to provide a printing function.

[0043] According to an embodiment of the present specification, the device information of the USB multi-mode device may include, for example, various information that can be used to match the device.

[0044] According to an embodiment of the present specification, the USB driver replacement policy can be used to indicate which USB devices need to automatically replace the driver. For USB devices that need to automatically replace the driver, as soon as the USB device is inserted into the USB interface of the terminal, the USB redirection driver is loaded for this device object, rather than waiting for the USB redirection service to perform the redirection operation. The advantage of this is that the driver replacement action during the USB redirection operation is avoided, and the device will not be reset during the redirection process, thereby ensuring that the working mode of the USB multi-mode device will not be changed to the initial USB storage mode due to the redirection operation.

[0045] Optionally, the device information may include, for example, at least one of a hardware identification and a compatible identification. Among them, the hardware identification may include a hardware ID. The hardware ID is a unique definition used to identify the hardware configuration of a computer or device. It can be generated by hardware information such as the motherboard, CPU, hard disk, etc., and the ID of each computer is unique. The hardware ID can help the system identify and match the corresponding driver to ensure that the device can work properly. The compatible identification may include a compatible ID. The compatible ID is a string defined by the device manufacturer to indicate that any driver package that claims to support the device can be used with a device with this ID. When the hardware ID of the device cannot accurately match the existing driver, the operating system can find a suitable driver package through the compatible ID to ensure that the device can work properly. The existence of a compatible ID improves the compatibility of the device and the success rate of device installation.

[0046] Correspondingly, the hardware identification and / or compatible identification of each USB multimode device can be recorded in advance in the USB driver replacement policy. Based on this, it can be determined whether the USB driver replacement policy contains at least one of the hardware identification and compatible identification of the USB multimode device. If the USB driver replacement policy contains at least one of the hardware identification and compatible identification of the USB multimode device, it is determined that the USB multimode device matches the USB driver replacement policy. Otherwise, it is determined that the USB multimode device does not match the USB driver replacement policy.

[0047] Optionally, after the USB multimode device in the first mode is redirected to the cloud desktop using the USB redirection driver, if the cloud desktop has not installed the second mode driver, the second mode driver can be installed. In this embodiment, the first mode may include a USB memory mode, and when the USB multimode device is in the USB memory mode, it is identified as a USB memory. Based on this, the terminal device can obtain the second mode driver from the USB multimode device in the USB memory mode, and then send the second mode driver to the cloud desktop, and then the cloud desktop installs the second mode driver.

[0048] Optionally, after installing the second mode driver, the cloud desktop can use the second mode driver to control the USB multi-mode device to switch the mode, so as to switch the device mode from the first mode to the second mode. Based on this, the cloud desktop can use the second mode driver to generate a mode switching instruction, and then send it to the USB multi-mode device via the terminal device, so that the USB multi-mode device switches from the first mode to the second mode according to the mode switching instruction.

[0049] After receiving the mode switching instruction, the USB multi-mode device will reset to switch the mode. During the reset, the USB multi-mode device is first ejected and then reinserted. After detecting that the USB multi-mode device is ejected, the terminal device can cancel the redirection of the current USB multi-mode device to the cloud desktop. After the USB multi-mode device is reinserted, the USB multi-mode device switches from the first mode to the second mode. After the terminal device detects that the USB multi-mode device is reinserted, it can reload the USB redirection driver, and then use the USB redirection driver to redirect the USB multi-mode device to the cloud desktop.

[0050] like Figure 3 FIG. 1 is a flowchart of another method for redirecting a USB multi-mode device according to an exemplary embodiment.

[0051] Exemplarily, in this embodiment, the terminal device may include an operating system, a USB redirection service, and a cloud desktop client (referred to as the client). The server may include a cloud desktop operating system. The USB multi-mode device may be a multi-mode printer.

[0052] In this implementation, the method for redirecting a USB multi-mode device may include the following steps:

[0053] After the cloud desktop client is started, it will send a USB policy to the terminal's USB redirection service. This policy will specify which USB devices need to have their drivers automatically replaced. After receiving the USB policy, the USB redirection service will send it to the USB filter driver.

[0054] After the USB multi-mode device is inserted into the terminal, the USB multi-mode device is initially in the first mode (USB storage mode).

[0055] The USB filter driver in the terminal operating system kernel determines whether the device information of the USB multi-mode device matches the USB driver replacement policy. If the device information matches the USB driver replacement policy, the USB redirection driver corresponding to the USB multi-mode device is loaded. Then, the terminal operating system broadcasts the device insertion event. The USB redirection service listens to the device insertion and prepares to perform USB redirection. The newly inserted device has already loaded the USB redirection driver, so USB redirection can be initiated directly without resetting the device to replace the driver.

[0056] The USB redirection service of the terminal redirects the USB multi-mode device to the cloud desktop. A corresponding virtual USB device is added to the cloud desktop, and its device mode is the first mode, so the cloud desktop operating system will load the first mode driver for it. Exemplarily, in this embodiment, the first mode can be a USB storage mode, and correspondingly, the first mode driver can be a USBstorage driver.

[0057] If the second mode driver is not installed in the cloud desktop, you need to install the second mode driver in the cloud desktop. For example, the cloud desktop can use the USB storage driver to obtain the second mode driver from the USB multi-mode device in USB storage mode via the terminal. Then the cloud desktop loads the second mode driver. If the cloud desktop has previously installed the second mode driver, the installation step is omitted.

[0058] The second mode driver can send a switching mode instruction to the USB multi-mode device to switch the device working mode to the second mode. The switching mode instruction is forwarded layer by layer through USB redirection and finally sent to the USB multi-mode device connected to the terminal.

[0059] The USB multi-mode device is reset according to the switch mode instruction. During this reset process, the USB multi-mode device is first ejected from the terminal operating system and then inserted. Therefore, the terminal operating system will broadcast the device unplugging event and the device plugging event one by one.

[0060] The USB redirection service of the terminal monitors the device pop-up event, cancels the redirection of the USB multi-mode device, and returns the USB multi-mode device to the terminal. Then, the USB multi-mode device is reinserted into the terminal, and the USB multi-mode device is now in the second mode. In this embodiment, the second mode can be a printer mode. Because the USB filter driver of the terminal judges according to the policy, the system automatically loads the USB redirection driver. Therefore, after receiving the device insertion event of the USB multi-mode device, the USB redirection service of the terminal directly uses the USB redirection driver to redirect the USB multi-mode device to the cloud desktop without resetting the device.

[0061] Because the device is not reset again, the virtual USB device added to the cloud desktop after redirection will maintain the same second mode as the terminal USB multi-mode device, and the cloud desktop will load the second mode driver for it accordingly. For example, in this embodiment, the USB multi-mode device is switched to printer mode, and the cloud desktop operating system will correctly identify the USB multi-mode device as a printer device and load the corresponding printer driver for it.

[0062] Corresponding to the embodiments of the aforementioned method, this specification also provides embodiments of a redirection device for a USB multi-mode device and a terminal to which it is applied.
