Question about Computers & Internet
The problem seems to be with your USB port on either end. If you use your USB port (PC end) rarely then there's a chance of corrosion/oxidization that has formed on the contacts. Use a little bit of WD40. First take a small piece of good thick drawing paper (the ones used by kids in class to draw stuff on).
Fold it in such a way so as to fit it inside the PC's USB port. Now apply a few drops of WD40 oil on the paper's folded edge and insert the paper gently into the port and rub it (IN-OUT-IN-OUT) action. Now try connecting your cable & handset.
Assuming that you have a frint panel USB connector and if its still not working then there could be a loose contact problem with the 4 pin USB motherboard connectors. Switch OFF the PC, remove the side cover and see where the wires go on the motherboard from the front panel.
VERY IMPORTANT: CAUTION, BEFORE REMOVING THE 4 USB PINS FROM THE MOTHERBOARD, WRITE DOWN ON A PIECE OF PAPER THE SEQUENCE THEY ARE PRESENTLY CONNECTED AS YOU WILL HAVE TO RE-CONNECT THEM IN THE EXACT SAME MANNER. A WRONG CONNECTION WILL CERTAINLY DAMAGE YOUR MOTHERBOARD BEYOND REPAIR. THERE ARE 4 PINS: Refer Diagram Below:
Remove the pins one by one, apply a little WD40 in the sockets of the black, square cylindrical sockets and place them back and restart your PC.
It should work now.
