==Making it Work==
Expecting [[Conexant CX2310x]] to work, but this is still under investigation.

===Firmware===
The unit does not use an loadable firmware. 

===Drivers===
See [[Conexant CX2310x]].

=== Patch to get the cx231xx driver working ===

In the file ''drivers/media/video/cx231xx/cx231xx-cards.c'' go to struct usb_device_id cx231xx_id_table[] and add these two lines e.g. at the beginning of the definition:

<pre>
    {USB_DEVICE(0x1D19, 0x6109),
    .driver_info = CX231XX_BOARD_PV_XCAPTURE_USB},
</pre>

Here is a [http://streibelt.de/blog/2013/06/23/kernel-patch-for-cx23103-video-grabber-linux-support/ proof that it is working].

===Test System===
The device is connected to a multicore AMD A6-3500 system.
 > uname -a
 Linux media-center 3.5.0-27-generic #46-Ubuntu SMP Mon Mar 25 19:58:17 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

===Kernel Output===
The Kernel loads the newly provided drivers<br>
 > dmesg
 [11196.213937] usb 1-4: new high-speed USB device number 2 using ehci_hcd
 [11196.349182] usb 1-4: New USB device found, idVendor=1d19, idProduct=6109

 [11196.349213] usb 1-4: SerialNumber: 0000000000

===Kernel Modules===
To get the difference the lsmod was logged before and after plugging in the device, then the "diff" command creates the output.
 
Remains to be filled in. Currently no difference found.

===Remote Control Support===
There is no remote control.

===Snapshot Control Support===
The housing is equipped with an push bottom to initiate a video snapshot. Operating of this shows no effect in VLC application nor /var/log/messages.
