A hybrid ATSC USB 2.0 device by Hauppauge.

The digital side of the device is supported under Linux since kernel 2.6.26. Analog support was merged into the mainline v4l-dvb tree on March 18, 2009.

Note: This device, the HVR-950Q, is significantly different from the older HVR-950 model, so please be sure to differentiate between the two. For information on the older model, see the WinTV-HVR-950 article.


Overview/Features

The device supports NTSC, 8-VSB and QAM.

Components Used

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

Identification

Output of lsusb -v:

Making it Work

Firmware

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

Note: The firmware is now bundled with Ubuntu 9.10 (Karmic), so users of that distro/version and newer do not need the following steps.

 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.

The firmware will be added lazily (on-demand) when you first use the driver.

Drivers

The xc5000 driver needed for this WinTV-HVR-950Q 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.

Note: the HVR-950Q has known issues with MythTV that prevent it from working. These are being actively worked by the 950q maintainer (Devin Heitmueller). Keep an eye on the KernelLabs blog for status updates: KernelLabs Blog

Sample Kernel Output

After you plug-in the device on a USB 2.0 port (it won't work with a USB 1.1) and use the driver for the first time (eg, by scanning channels), you may see something like this on dmesg:

After an application open the device the first time, the module will load the firmware. You will see:
