Hauppauge WinTV HVR 900 (M/R 65018/B3C0) doesn't work anymore since linux 3.6.6

[Philippe Valembois - Phil]

Hello,
I have posted a bug report here :
https://bugzilla.kernel.org/show_bug.cgi?id=50361 and I have been told
to send it to the ML too.

The commit causing the bug has been pushed to kernel between linux-3.5
and linux-3.6.

Here is my bug summary :

The WinTV HVR900 DVB-T usb stick has stopped working in Linux 3.6.6.
The tuner fails at tuning and no DVB channel can be watched.

Reverting the commit 3de9e9624b36263618470c6e134f22eabf8f2551 fixes the
problem
and the tuner can tune again. It still seems there is some delay between the
moment when the USB stick is plugged and when it can tune : running
dvbscan too
fast makes the first channels tuning fail but after several seconds it tunes
perfectly.

Don't hesitate to ask me for additional debug.

Regards,
Philippe Valembois

Does this also fail on Linus's tree?  If so, this patch should be
reverted from there too.

Hello,
sorry for the late reply, I finally compiled fresh Linus' tree and did a
fast test : it seems to work. I will now try to find the commit that
made it work so you can maybe commit it in the stable branch?

Hi,
I did new tests on the 3.6.6 kernel and can't make tuner fail anymore. I
don't understand, it was failing several times and now, nothing...
I re-extracted the kernel to be sure I didn't left some modifications
but it's still working.
Sorry for the disturbance,

Regards,
Philippe Valembois

There is multiple models of that device. What is your device USB ID?
What it outputs to the system log when stick is plugged? Use dmesg 
command to see and copy paste output.

Your device supports DVB-C, DVB-T and analog? You tested only DVB-T?


I just tested quite many em28xx based sticks with stock 3.6.6 and all 
seems to work just fine. All em28xx devices I have here are digital 
only, which makes me wonder if it has something to do with hybrid 
devices (digital + analog)...

Antti
