I will start by saying that I have search the forums and not found this issue. When I connect my droid to my PC everything functions as it should (including RadioComm), except for the USB mass storage. When connected and USB mass storage is selected it my PC doesn't recognize the internal memory or the SD card. The device manager sees them as WPD FileSystem Volume Driver but with a Device cannot start. (code 10) error. What I have tried. Factory USB cable, other known good cables. Updating drivers, and reinstalling MotoHelper with drivers. Every different USB slot on my PC. Uninstalling everything and starting from scratch including rebooting PC. This is a problem with my PC only. I am having no problems with connection to my laptop, it's just a pain transfering things to the laptop to put on the phone. PC is running Windows 7 32 bit. Laptop is running Windows 7 64 bit.
