EMP202 chip inside Terratec Grabby (hw rev 2) seems to require some time
before accessing reliably its registers. Otherwise it returns some values
previously put on the I2C bus.
To account for that period, we delay card setup until we have a proof that
accessing AC97 registers is reliable. We get
Thanks Mauro for commenting on my work.
With respect to first version, I've:
* added a timeout mecanism as requested
* added an extra check to avoid cases when the same value is constantly
returned no matter which register is accessed.

To test this:
* modprobe em28xx-alsa
* connect Grabby

Hi all,
my first post
I am a Linux user who bought a Terratec Grabby 2 analog-video-to-usb
encoding device, which I cannot get to work on Linux.
I noticed a thread on this mailing list a few weeks ago.

Since USBPcap 1.0.0.3 release there is digitally signed driver and

Now I'm using 3.9.0 with the above mentioned patchset, and my
additional patch (below). This seems to work nicely.
In any case it strongly looks like Terratec Grabby hwrev2 has also

Hi Mauro,
with the help of Bernd Spaeth, I finally managed to get the Terratec

Hi,
The sound comes from alsa device. Several em28xx types provide
standard USB audio. So,
snd-usb-audio handles it. That's why you need
