I have a portable hard drive that i attach to my computer via USB.
It has worked fine so far but now when i plug it in the only response i get a message saying "USB device not recognized, one of the devices attached to this computer has malfunctioned....." and under Device Manager in Universal Serial Bus Controller Ican see not 1 but 2 Unknown Devices.
If I uninstall them both, unplug the hard drive from the usb port and do a Scan For Hardware Changes then I will get the message "Unkown Device. Device Driver Software installed successfully" and one unknown device will reappear in the Universal Serial Bus Controller.
Now I wonder: what device is that?? Clicking on properties doesn't really help
Plugging in the usb hard drive will bring again the error message "USB device not recognized....." then "Unknown device. Device driver software installed successfully" and the unknown devices number in Device manager back to 2.
The usb hard drive works fine on other computers so that is not the problem
Don't know if I have been very clear in describing the problem but any help would be appreciated.
