Hauppauge WinTV-HVR-850
From LinuxTVWiki
A group of hybrid ATSC USB 2.0 devices by Hauppauge.
Note: There are three significantly different devices being sold under the same "HVR-850" brand name. The first two are supported, but the newest version (USB ID 2040:b140) requires kernel 2.6.37 and still has problems.

Overview/Features
There are three versions of this device.
- The first is essentially the older WinTV-HVR-950 model. Running lsusb -v will show the manufacturer:device code of 2040:651f.
- The second version is essentially a WinTV-HVR-950Q. Running lsusb -v will show the manufacturer:device code of 2040:7240.
- The third version is unique, model 1200 (Bought from Frys or Amazon). Running lsusb -v will show the manufacturer:device code of 2040:b140. Useful information for this version can be found on the discussion page. It has a known issue with the demodulator jamming the i2c bus. This can be worked around but not in analog mode.
Evidently, this device does not like USB 1.1 slots (see the discussion page).
Components Used (model 65301, 2040:651f)
Components Used (model 72301, 2040:7240)
- Xceive XC5000 (tuner and analog demodulator)
- Auvitek AU8522 (A/V decoder, analog demodulator [not used], and digital demodulator)
- Auvitek AU0828 (USB bridge)
Components Used (model 01200, 2040:b140)
Note: The following information currently outlines only that pertaining to the second version (i.e. the 950Q analog).

Making it Work
Firmware
In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000.
sudo wget -O /lib/firmware/dvb-fe-xc5000-1.6.114.fw http://linuxtv.org/downloads/firmware/dvb-fe-xc5000-1.6.114.fw
Note: Though the usual directory location in which the firmware file is placed is /lib/firmware, this may differ in the case of some distros; consult your distro's documentation for the appropriate location.
Drivers
The xc5000 driver needed for this WinTV-HVR-850 is already part of the latest Linux kernel (part of v4l-dvb drivers).
Analog support was merged into the mainline v4l-dvb tree on March 18, 2009.
