Example Embodiment
[0046] Example one
[0047] The embodiment of the present invention provides a method for improving the reading speed of a USB slave device, which is applied to a system including a USB host device and a USB slave device, wherein the method includes:
[0048] Step 1. Determine whether the USB slave device is connected to the USB master device, if connected, perform step 2, and if not connected, end;
[0049] Step 2. The USB slave device binds the endpoint to a memory matching the endpoint;
[0050] Step 3. The USB slave device receives the data sent by the USB master device, and stores the data in the memory bound to the endpoint;
[0051] Step 4. The USB slave device unbinds the memory from the endpoint, and if the data transmission has not ended, step 2 is executed again until the data transmission ends.
[0052] Further, the step 1 includes:
[0053] The USB host device automatically detects the USB port;
[0054] If a USB slave device is detected, the USB slave device is connected to t...
Example Embodiment
[0073] Example two
[0074] Such as figure 2 As shown, figure 2 It is a schematic flowchart of the method provided by the embodiment of the present invention. The embodiment of the present invention provides a method for improving the reading speed of a USB slave device, which is mainly applied in the data interaction process between the USB host device and the USB slave device. The specific content is as follows:
[0075] Step 1. Determine whether the USB slave device is connected to the USB master device, if connected, perform step 2, and if not connected, end;
[0076] The specific judgment process is as follows:
[0077] The USB host device automatically detects the USB port,
[0078] If a USB slave device is detected, the USB slave device is connected to the USB host device;
[0079] If it is not detected, it is not connected.
[0080] It should be noted that, in the embodiment of the present invention, after the USB slave device is detected, the following content is also includ...
