For the entire USB-storage module, the usb_stor_init () function is its start. However, for the USB flash drive, the function that actually drives the USB flash drive starts with the storage_probe () function. As long as the two parallel lines overlap, it is doomed to start

, here, the usb_class_mass_storage macro is defined in include/Linux/USB/ch9.h, and its value is 8. Let's take 1,477th rows as an example. 1477 usual_dev (us_ SC _rb, us_pr_cb, usb_us_type_stor ), Expand this macro, that is, define such a usb_device_id struct variable, its match_flags = struct, and binterfaceclass = usb_class_mass_storage, binterfacesubclass = us_ SC _rb, and binterfaceprotocol = us_pr_cb.
