Hello all,
First, a disclaimer - I am very new to driver development, so please bear with my ignorance.


I am trying to write a device driver for a USB U401 from usbmicro.com. The device works by sending a control packet to the device, then receiving an interrupt packet back. I have (I think) the send portion down pat, but I have yet to get the response URB correctly. I am trying to receive the URB by calling usb_fill_int_urb() and then usb_submit_urb() on the URB. I receive a -ENXIO from usb_submit_urb(), and the urb->status found in the callback function is -ENOPIPE. I'm not real sure what additional info I need to send, so please tell me if I need to give more info.

Ian
