Hello everybody, I have some USB WLAN device (based on the Atmel AT76C503A) which works when connected to a UHCI host controller, but not with an OHCI. I know that this would be a question for the driver developer in the first place, but the respective mailing list is long dead, so I tried to fix it myself and ran into some problems.
When transmitting data, the driver first builds an URB with usb_fill_bulk_urb and sends it via usb_submit_urb. In the callback, urb->status is checked and if not zero, the packet error counter is increased - which happens at least half of the time. I've put in a printk to check the error code, it's -110, and that is supposed to be ETIMEDOUT. According to ohci.h, this code is returned on TD_DEVNOTRESP.. but now, I'm out of clues. Is this error code really caused by some kind of timeout? If so, does anybody know how to give the device a bit more time to process the URB?
