Not Validated boards

What's it?

 Not validated means: that your device was added to kernel but
 no developer has the hardware to test. If you would like to help
 and inform that your hardware works (or not) please see the section
 How to validate my vendor/product id at upstream kernel

How to validate my vendor/product id at upstream kernel?

  • Example:
 From: foobar
 To: linux-media@...
 Subject: em28xx: new board id [0b1a:2821]

 Hi, 

 I've made tests with my Pixelview board:

 Model: Prolink PlayTV USB 2.0
 Vendor/Product id: [0b1a:2821].

 Tests made: 

     - Analog [Worked]
     - DVB    [this board doesn't support dvb mode]

 Tested-by: foobar <foobar@foobar.com>

 ~foobar

Otherwise, if you had any issue, please contact linux-media mail-list.

If some features doesn't work (i.e: audio, dvb, s-video)

Should I call whom?

 Please contact linux-media mail-list.

About em28xx models

em2800/em2820/em2821/em2840

  • used on older analog only device designs. These chips have support for USB Audio Class; so, audio module is snd-usb-audio

em2820/em2840 based devices

em2860

EM2860 supports Video decoder Audio decoder and VBI

em2860 based devices

em2863 based devices

em2870/2871/2872/2873

  • supports DVB/ATSC (but with no analog support). This is targeted at digital only devices.

EM2870 devices include:

em2874

  • next generation version of the em2870 design - they moved around a bunch of registers compared to em2870/2880 and the chip itself supports two transport streams (although most designs will probably only use one stream).
  • KWorld UB435-Q USB ATSC TV Stick

em2880/2881/2883

  • supports DVB/ATSC. Doesn't provide USB Audio Class. Instead, digital audio is provided via an USB Vendor Class; so, these chips require the em28xx-alsa module for digital audio to work.

em2880 based devices

em2710/em2750 based devices

em276x/em277x/em278x based devices

  • latest bridge generation for camera devices
  • optional UVC (USB video class) support
  • supports MPEG video format
  • supports several advanced camera functionalities, such as autofocus, image statistics etc.


Known devices:
SpeedLink VAD Laplace webcam (em2765 + OV2640)

em25xx

  • seems to be the Chinese market versions of the em276x/7x/8x bridges

em28284

Feature Support

  • No firmware is required for em28xx ICs ... note: though em28xx based devices paired with some tuners will need firmware for the tuner (i.e. there are em28xx based devices paired with a XCeive XC3028 or XC2028 tuner, which require a generic firmware from Xceive).

About Driver

  • Development -- originally by four: Ludovico Cavedon, Markus Rechberger, Mauro Carvalho Chehab, Sascha Sommer.
  • One of the authors, Markus Rechberger, is now developing only closed source binary drivers.
