Salvaged from an MS system. The manufacturer stated that neither Linux nor Mac were supported. In fact, Skype couldn't recognize it in Mint 12 Lisa.
I managed to put it to work with Skype using v4l2ucp and a few tweaks, as shown in the tutorial: «How to make Webcam compatible with Skype» (by frankeinstein).
It works. The picture from this device is... as poor as in the native ms windows environment!
