Hi folks,
Got a "Hauppauge USB Live 2" after google found me that there is a linux
driver for it. Unfortunaly linux doesn't manage to initialize the device.
I've connected the device to a Thinkpad T60. It runs a 2.6.37-rc5 kernel
with the linuxtv/staging/for_v2.6.38 branch merged in.
Kernel log and lsusb output are attached.
Ideas anyone?
Looks like a regression got introduced since I submitted the original
support for the device.
Mauro?
No idea what happened. The driver is working here with the devices I have.
Unfortunately, I don't have any USB Live 2 here for testing.
Based on the logs, maybe the driver is directing the I2C commands to the
wrong bus.
The better would be to bisect the kernel and see what patch broke it.
The support for USB live2 were added on changeset 4270c3ca.
There aren't many changes on it (45 changes), so, bisecting it shouldn't be hard:
$ git log --oneline --no-merges 4270c3ca.. drivers/media/video/cx231xx
f5db33f [media] cx231xx: stray unlock on error path
Using that commit directly looks better. I still see the
UsbInterface::sendCommand failures, but the driver seems to finish the
initialization and looks for the firmware. So it seems something
between -rc2 and -rc5 in mainline made it regress ...
cheers,
Gerd
