=== Not Validated boards ===
==== What's it? ====
Not validate means: that your device was added to kernel but the developer(es) doesn't have the hardware for tests.
If you would like to help and inform that you hardware work (or not) please see section

==== How to validate my vendor/product id at upstream kernel?====
* Send your board name, lsusb output and tests made to [http://www.redhat.com/mailman/listinfo/video4linux-list video4linux mail-list]<br>

* Example:

From: foobar
'''To''': video4linux-list
'''Subject''': em28xx: new board id [0b1a:2821]<br>
Hi, <br>
I've made tests with my '''Pixelview''' board:<br>
'''Model''': Prolink PlayTV USB 2.0
'''Vendor/Product id''': [0b1a:2821].<br>
'''Tests made''': <br>
- Analog [Worked]
- DVB [this board doesn't support dvb mode]<br>
'''Tested-by''': foobar <foobar@foobar.com><br>
~foobar<br>
Otherwise, if you had any issue, please contact [http://www.redhat.com/mailman/listinfo/video4linux-list video4linux mail-list].

== If some features doesn't work (i.e: audio, dvb, s-video)==
===Should I call whom?===
Please contact [http://www.redhat.com/mailman/listinfo/video4linux-list video4linux mail-list].
===Usbsnoop===
If you were asked to sniff your device, use this [http://www.linuxtv.org/v4lwiki/index.php/Usbsnoop instructions]

==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===
* [[Gadmei utv 310]]
** [[Em2820:Talk]]
* [[Pinnacle_PCTV_USB2]]
* [[V-Gear PocketTV]]
* [[USBGear USB2.0 Video Adapter With Audio (VD204)]]

===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
* [[Pinnacle PCTV unidentified DVB-T USB device]]
* [http://videologyinc.com/cameras/ccd-board-camera-20K14XUSB.htm Videology 20K14XUSB webcam]

===em2750===

==Some Misc stuff==
The following needs to be cleaned up and/or integrated into the article:
* [[Em2880 EEPROM Data]]

* [[Em2880/remote]]

==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 [http://www.linuxtv.org/wiki/index.php/Xceive_XC3028/XC2028 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.<br>
* One of the authors, Markus Rechberger, forked the upstream project.
