H A D | usb.c | 7839f5f8 Fri Jun 17 01:18:11 CDT 2016 Peng Fan <van.freenix@gmail.com> cmd: usb: check if_type before using this device For legacy usb storage driver, USB_MAX_STOR_DEV is defined as 7. If we only have one usb disk on board, `usb dev 0` is ok. But if `usb dev 1`, still ok, then `usb read xxx` will trigger system fault and reboot. So check if_type before using this device.
