The device is is a WIFI USB 2.0 device, it use the same USB slot, so I
think the USB controller could work fine now. The error message as fllowing
:
usb 1-1.4: device descriptor read/64, error 2
usb 1-1.4: new full speed USB device using musb_hdrc and address 5
usb 1-1.4: device descriptor read/8, error 2
usb 1-1.4: device descriptor read/8, error 2
usb 1-1.4: new full speed USB device using musb_hdrc and address 6
usb 1-1.4: device descriptor read/8, error 2
usb 1-1.4: device descriptor read/8, error 2
I think the USB controller couldn't find the right dirver, so it
display these error message.
