Mini pro not recognized by PC

[Hackeberga]

Hi,

I have a mini pro SK171 with android 4.0.4 Recently (after an android update?) I started experiencing this problem: there seems to be no communication between The PC (with Vista as the operative system) and my mobile. Earlier as soon I connected the mobile it was immediatly  recognized, now nothing.

If I in the mini pro go to "connection sharing and hotspot" the USB option to select the sharing via usb cable is inactivated (it can't be selected), and it says: "no USB is connected (this despite the calbe is connected and is actually charging the mobile phone from the PC.

Any suggestions?

Thanx
