A small USB Video signal analog to digital converter distributed from the German discounter chain "Lidl". Vendor: TARGA GmbH, Lange Wende 41, D-59494 Soest. Artikel Nr.: 32973. SilverCrest VG 2000. TARGA-Nr.1479836. GTIN (former EAN) is 4250133701701. This device has no TV nor Radio receivers.
It works under Linux.

Take note: a new batch being sold by Lidl late 2012 called SilverCrest USB 2.0 Video Grabber SVG 2.0 A2 and looks exactly similar and has the same packaging, but uses a different chipset (Conexant CX23103-11Z), identified as ID 1d19:6109 by Dexatek Technology Ltd. The batch sold in 2010 called VG2010 ID 1d19:6105 has a chipset AF9035. The chipset support for AF9035 ID 1d19:6105 has to be enabled in the kernel modules. The kernel driver has to be amended to support the ID 1d19:6105.

Making it Work

In a openSUSE 11.3 Box the v4l kernel tree must be updated, following the installation instructions written in Em28xx devices. The update process is working without any problems. After installing the updates and plugging the devise the modules where loaded.

When testing it with VLC media player the video or audio is working by selecting the new devices. In order to get sound with the video frames, the "/dev/video0" have to be manualy selected as video input device and "plughw:1,0" also manualy as audio input an my system.

Other applications, as motv, will display the video pictures, but no sound.

Firmware

The unit does not use an loadable firmware.

Drivers

See Em28xx devices.

Test System

The device is connected to a multicore Intel X86_64 system.
