Can I test a USB port with a multimeter?
If you just want to check that +5V is being supplied, you would connect the hot wire to the red lead of your multimeter plugged into the V(&Omega;)mA position and the ground wire to the black lead of your multimeter plugged into the COM position. Set the Multimeter to DCV 20 mode and it should show around 5V.

If that works, then another test you can do is get a 1.5kohm resistor and connect it between either of the data wires and the hot wire while your computer is on. Your computer should say something like "USB device not recognized" or something to that effect.

Obviously, be careful not to short any of the wires together while you're doing this.
