Hi, After a big rewriting of iuu_phoenix, I have the following problem. The polling is well working with callback mechanism but only during 30 seconds maximum. After sometime, The read_bulk_callback give me an urb-status EOVERFLOW... Is the polling running to faster than the device can support ? Is there a way to slow down the polling ? The only way to recover is to reset the device ( usb_reset_device )

Whatever it wants. Usually it's correct to keep waiting for the deice to provide the data. > Does the driver timeout and abandaon the transaction in such a case ? It could, but that's rarely appropriate. > Which code fragement in the driver handles this case. Whatever sets a timer to unlink (or kill) the URB when it times out. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
