My girlfriend has a no-name bluetooth usb dongle (she bought it some time ago since her laptop came without the bluetooth integrated and she needs it to access stuff on her cellphone). It worked perfectly on her Windows 7 machine until recently. Now, by looking into the Device manager this is what we see:
And now when she connects the dongle to the USB port it does't work. I've tested it: I connected the dongle to my old XP machine and there it worked fine - and instantly. So the thing itself is OK.
I tried uninstalling the devices from her computer but when they reinstall it says that the driver installation was unsuccessful. I also tried seraching for the driver by the Hardware ID but found nothing that would work.
Do you guys have any idea how to fix this?
