Embodiment Construction

[0023] Please refer to FIG. 1 to FIG. 2 , wherein FIG. 1 shows a system block diagram of a preferred embodiment of the present invention that can execute a file system call on a USB bus; FIG. 2 shows a system that can execute a file system on a USB bus in the present invention. Schematic diagram of the system flow of the call.

[0024] As shown in Figure 1, the system of the present invention that can carry out file system call on USB bus, it comprises: a slave USB device 10; A file system (FS) USB driver 20; A file system (FS) USB master The driver 30; a host USB device 40 and a disk-level driver 50 are combined.

[0025] Wherein, the slave USB device 10 is, for example but not limited to, a video recorder (Video Recorder) with a USB interface. There is a file system client application (file system client application) 11 on the slave USB device 10 to generate a file system call (file system call), so that the image data captured by the file system call is stored in another ...

Abstract

The invention relates to a system which can be used on a USB bus to execute file system call; the system comprises a slave USB device which has a file system client application to generate a file system call, an FSUSB driver which can receive the file system call and covert the file system call into an FSUSB agreement packet, an FSUSB main driver which can receive the FSUSB agreement packet and generate a corresponding file system call, a master USB device, as well as a disk-level driver which can accept the control of the master USB device to access a disk I / O bus; therefore, the slave USB device can also execute the file call on the USB bus. In addition, the invention also provides a method of executing file system calls on the USB bus.

Description

technical field [0001] The present invention relates to a system and method capable of executing file system calls on a USB bus, in particular to a system capable of executing file system calls on a USB bus that allows a slave USB device to execute a file system call without passing through a master USB device A system of file system calls and methods thereof. Background technique [0002] According to the current USB protocol, when the slave USB device (Slave USBdevice) wants to generate a file system call (file system call), it needs to pass through a host USB device (Host USB device) to perform file system on the external disk storage device. call. With such a structure, the slave USB device must pass through a master USB device to execute a file system call to another slave USB device to read or write files. But this will increase the workload of the main USB device, which is really a fly in the ointment. Contents of the invention [0003] In order to solve the shor...
