Which USB port? There have been issues in the past where certain USB3.0 ports actually are the issue. Try a standard 2.0 port and run your driver install again (assuming you haven't already).
I had a similar issue at first myself- turned out being the usb3.0 chipset itself (first gen not integrated to the PCH yet).
If you do have this installed in a 2.0 port... where did you get these erupters?
The front, the machine I'm using doesn't have any USB 3.0.
All of the instructions I can find online say to install the drivers
before you actually plug them in, that's why I'm so confused. I feel as though it might be something with the machine that I'm using?
