Try using , 'device not detected' in windows device recovery tool , also wait 5mins until the computer identifies it , maybe it's just a matter of time

There may be a problem with the phone drivers. Make sure the drivers are installed. Once i had the same problem and i tried to recover the phone from a win7 pc. It worked. Mine was win8.1

when I hook phone to pc with any cable it says usb malfunction so it wont let recovery detect it how can I make sure the drivers are installed x#

Other possibilities:
The usb cable has gone bad.
The usb port on the phone has gone.
The usb port on the PC is malfunctioning.
Try a different usb port or try the cable and phone on another computer to rule out cable and phone usb port being damaged. Any updated usb drivers for the computer?

When the phone is not detected, remove from USB cable, turn it off then reconnect. Mine was detected after a few misses - Nokia 630 dual sim.
