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

• Em2820/gadmei utv 310
  • Em2820:Talk
• Pinnacle_PCTV_USB2
• Em2820/pinnacle
• Em2820/vgear

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

• KWorld 350U DVB-T
• KWorld DVB-T 355U
• KWorld 310U
• KWorld USB2800
• Em2880/PinnaclePCTV
• Videology 20K14XUSB webcam

em2750

• Seem to be used by some Webcams.

Some Misc stuff

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

• Em2880/Eeproms
• Em2880/Todo
• Em2880/remote

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.

  • mrec's page on the em2880 ... note: that the information seems heavily tied to devices which utilise a xceive xc3028 tuner ... hence you may also want to read his xc3028 page for related info
