Sometimes one can establish a connection with the scanner but often not. It is really a trail-on-error happening. Are you lucky to have an connection, the result of the scanner is poor and not usable (various gray bars on scan).
I was very enthusiastic about VirtualHere but it dropped dramatically fast and for me not usable at this stage.

Read often that it could be a power supply issue of the Raspberry. That why I'am using a 5.2 Volt adapter. But still it is not stable.
