Dear Oliver, 1. please don't send zipped attachments to the list Ok. I am so sorry about it.
2. What precisely are you doing to cause this? Merely loading the driver?Ifconfig? I called the FILL_BULK_URB, then I called the submit_urb function. After that, I got the error. 3. Which kernel version? Kernel version 2.4-14.18 (red-hat 8) 4. Did you try to enable USB debugging? No. And how can I enable it? With many thanks, Harry > Am Dienstag, 13.
