A DECENT picture of the smaller chip near the USB port of the Arduino or the writing on that chip may be nice to have so somebody can say for sure about drivers etc..
Attaching a clean up procedure for IDE's that seems to help quite a few people.
For a few years now USB ports have had decent isolation from over current and such and a simple test is to plug a known working devices such as a mouse into each on in turn and see if it works. (eliminates that aspect completely)
Use of COM 2 is unusual for windows as COM 1 and 2 are normally reserved for windows use.
USB 3.0 is not always recommended for Arduino boards as it has been shown to cause some issues (chipset dependent) so make sure you are testing on a USB 2.0 port.
