Hello,
I have upgraded my testing system with cx25821 based video capture card to
system (OpenSuSE 12.1)
with kernel 3.4.4 and driver for cx25821 doesn't work. Previous system was with
kernel 2.6.37 (OpenSuSE 11.4)
with this patch http://patchwork.linuxtv.org/patch/10056/ and manualy compiled
module. With kernel 2.6.37
driver works properly.
Now I can see, that driver is loaded, but no device in /dev/ are created.
Please take a look for attached
outputs:
