Just as first,
uninstall the unknows device of your hardware config, connect the phone again, and install the drivers manually, so dont use auto install...
when u have done this, just remove the cable out of the phone, and put it in again after 30 seconds.
if it's ok, it will be ok.
from then on you can flash your phone!
if its not working your bootloader is ****ed up, or try another USB port on the pc otherway your cable or port(on phone or PC)) will be not good...
other way to do it, just install windows xp pro insteed of home...
install active sync, and put the usb cable in the pc and in the phone, it will help alot...
It can be that u have to try another cable if u buy an mp3 player or digital camera, almost all cables are the same as the usb cable of the prophet you can try this cables also to get it working!!
Windows XP Home edition doesnt find this drivers everytime.
Windows XP Pro will have no problems at all...
