Jump to navigation Jump to search

A hybrid ATSC USB 2.0 device by Hauppauge.

Note: There are three significantly different devices being sold under the same "HVR-850" brand name. All three versions are supported, but the newest version (USB ID 2040:b140) requires kernel 2.6.37.

Overview/Features

The second version is essentially a WinTV-HVR-950Q while the first is essentially the older WinTV-HVR-950 model, so buyer beware.

Note: The following information currently outlines only that pertaining to the "Model 1200" version (i.e. the 950Q analog).

Evidently, this device does not like USB 1.1 slots (see the discussion page).

Components Used

  • Xceive XC5000 (tuner and analog demodulator)
  • Auvitek AU8522 (A/V decoder, analog demodulator [not used], and digital demodulator)
  • Auvitek AU0828 (USB bridge)

Making it Work

Firmware

In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000.

 wget http://www.steventoth.net/linux/xc5000/HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip
 wget http://www.steventoth.net/linux/xc5000/extract.sh
 sh extract.sh
 cp dvb-fe-xc5000-1.1.fw /lib/firmware

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.
