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

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

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

em2750

Some Misc stuff

The following needs to be cleaned up and/or integrated into the article:

Feature Support

  • in-kernel em28xx driver: radio and analog TV (including broadcast audio) are working fine. Support for DVB/ATSC is not present yet.
  • 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 4 Ludovico Cavedon, Markus Rechberger, Mauro Carvalho Chehab, Sascha Sommer.
  • One of the authors, Markus Rechberger, forked the upstream project.
