André,
I'm leaving the question intact for context, and adding some folks.

I am sorry to disturb you because of the old stk1160 driver, but I am very
stuck and did not find any answer googling for more than 2 hours...
If you could give me a tip I would be very glad! I am trying to use your
driver on a cubieboard2 with ubuntu 12.04. If I try sudo make I always get the
following error:
/lib/modules/3.4.79-sun7i+/build: No such file or directory.
You're probably using the backported driver, uh? Any chance you use a
newer kernel (> v3.7) ?
Probably not if you want a functional system :)
Do you have any idea? I definitely have a build in the modules directory...
You most likely have a broken symlink there. You (or someone else)
probably cross-built the kernel but didn't install the kernel headers
there. You should install them to build stk1160 on the cubieboard2 (or
cross build stk1160 as well).
Emilio? Hans? Do you think the USB on the cubieboard2 can transfer
uncompressed (raw) video?
stk1160 needs as much as 20 MiB/sec. on isoc URBs and so far I haven't
seen many embedded systems
possible of that throughput...
Should be ok I suppose; with a USB hard drive I get these unscientific
results:
emilio@mele:~$ echo 3|sudo tee /proc/sys/vm/drop_caches
3
emilio@mele:~$ LANG=C sudo -E dd if=/dev/sda of=/dev/null bs=4M count=200
200+0 records in
200+0 records out
838860800 bytes (839 MB) copied, 26.8201 s, 31.3 MB/s
(That's on a Host port; the OTG port is musb and would probably get
around half that performance from what I've heard).
Cheers,
Emilio
