Hello list,
the kobil_sct driver requires interrupt-out transfers to write the data
to the device. This works fine with the ochi hcd, but fails with the
uhci hcd. I attached the output from /var/log/messages.
usb_submit_urb returns -22 (-EINVAL).
I tested it on a centrino notebook, but it should fail with all PC with
uhci host controller.
So what must I do to fix the driver?
(Or is it a bug in the uhci hcd?)
Why do the ohci and uhci behave different?
Kernel is 2.6.4-52 (SuSE 9.1 dist)
I'm not in the office until 19th of May. So it could take some time
until I can response.
Many thanks in advance
Thomas Wahrenbruch
