Hey there,

You might find this funny but from my experience I belive its a software thing or some kinda low level firmware related issues only after updating have I experienced this to Winmo6.5. I know it sounds strange but I have had this several times but only after flashing the unit . I put the unit into bootloader mode from serial to usb and the I see the connection when I connect the cable on the phone and the computer . It makes a connection but windows on the computer dont see it and the device some kinda of communication error of sort. So I researched this over and over and it only came down to updating the device has caused this. So with that being said as a last resort I opened the unit reflowed the Usb port. It worked in my situation. It was purely a last ditch effert and the usb connection was there(soldered) , it worked for me hope this helps .
