Hi Mauricio,

Disable CONFIG_USB_DEBUG for now to get the driver working.

Someone needs to investigate the problem: USB core dislikes
URB_ZERO_PACKET flag for bulk pipes. Such flag is set to send a final
zero packet to finish the transfer.

Now I have no idea if such packet is needed by some host controllers, or
simply unnecessary.

Thanks!
