The reason is of course to use this to deploy some operating systems, especially USB flash drives (you can also use

After sorting and digesting the device model, you have the foundation to compile a device driver program. You need to be familiar with the driver of the USB device because of the working relationship. Therefore, select the driver of the USB device as the start point.

As mentioned above, return to the usb_stor_acquire_resources () function and return 0. So we finally went back to the storage_probe () function. Row 3: The scsi_add_host () function is executed. The previously applied US-> host is passed to it as a parameter, and INTF-> Dev is also passed to it, this is used to register sysfs. As mentioned above, scsi_add_host () must be executed after scsi_host_alloc so that the SCSI core layer can know that such a host exists. If scsi_add_host () is successful
