[linux-dvb] Nova USB (dvb-s) - failed urb submission (0: err = -22)!

[Dominik Roettsches <d-r@roettsches.de>]

Hi,

I'm  new  to  DVB setup under linux bot I think I got quite far
and now I'm stuck.

What  I've  done so far. Compiled in the ttusb module in kernel
and the grundig frontend module and dvbcore and such.

When I connect the Nova usb device I get usb messages in syslog
and the ttusb device driver is correctly loaded.
After  that  is  done  I  manually do a modprobe of the grundig
frontend  driver.  Is  that  correct?  Or do I need a different
frontend driver or different module at all?

Anyway  if I did load the grundig frontend driver 'szap -r -n2'
for example can connect to the device and continously logs some
signal statistics.

Unfortunately  and  this  is  my main problem I get an error in
sylog:

Kernel  is  a  2.6.1 Vanilla (okay, one little radeonfb.c patch
:-) ) and using the kernel tree dvb code without modifications.

Anyone using WinTV Nova USB successfully under 2.6.x?
I'd be very glad, if anyone has some idea how to get rid of
this problem, thanks for your help in advance.

Dominik
