Hi Wim,
I have now tested both programs uvcscope & uvcview with the latest USB drivers from Lars (v10.202) and from AN (v11.13).
In both environments both programs starts but the video freezes after some seconds with the already posted error message.
I couldn't repeat the three minutes run time for uvcview.
I guess I shall try a clean environment, but that is a little bit tricky for the X250 because I have to clone the OS using DFSee.
If I have time I will give it another try and will stop for now testing the camera.
Hartelijk dank voor uw hulp.
Greetings form Potsdam/Germany,
Mike
