The kernel matches drivers to USB devices based on the descriptors 
stored in the device.  In your case, the the bInterfaceClass, 
bInterfaceSubClass, and bInterfaceProtocol values 0x08, 0x06, and 0x50 
match the usb-storage driver.

No, because usb-storage is already set to be a driver for your device.
