Please help with my nokia n8 - solution needed

[ovimaxxx]

Before analizing my nokia n8 the symtoms of the phone are the following: when trying to turn on it vibrates and nothing (blank screen, nothing): when connected to pc with original usb cable it sounds that it recognizes phone then immediately sounds like disconnecting it. Moreover the little led near usb blinks for a while then stops.
When I have connected my nokia n8 with mxbox orange and proper mxkey cable, run mobilex then, connected mx interface, nokia tool then hit scan - nothing appeared, hit bus check and obtain the following:
