I have the a USB WinTV HVR-850 by Hauppauge. This version has the LGDT3305 and the cx231xx, lsusb shows it as 2040:b140 Hauppauge.
With Ubuntu 12.04 the xc5000 and v4l-dvb firmwares had to be installed to get it to detect and work correctly. Now with Ubuntu 13.10 things are a little different. I've installed v4l-utils and v4l2ucp as well as the xc5000 firmware package.
dmesg | grep -i lg shows this:
usb 1-2: DVB: registering adapter 2 frontend 0 (LG Electronics LGDT3305 VSB/QAM Frontend
dmesg | grep -i firmware shows the device is using this firmware:
cx25840 6-0044: loaded v4l-cx23885-avcore-01.fw firmware (16382 bytes)
Randomly it will give and error message that the xc5000 firmware failed to download. However this does not appear to affect the operation of the tuner in anyway.
The main issue I'm having is with the cx231xx device after opening a closing MythTV frontend. Before launching frontend dmesg messages for this device are fairly clean as seen in the following attachment:
After launching the frontend and playing a file the same dmeg | grep -i cx231xx commands shows a different output, afterwards the is serious of messages added to the end.
How do I go about reporting this bug and who would it be reported too?
