Hi,
I was having a USB connect/disconnect issue with USB 2.0 ports. RehabMan suggested to check the ports with Windows to see if it's s/w or h/w issue, I completed the tests. The background information is here on another thread.
In short, all 4 USB devices (2x 3.0, 2x 2.0) work on USB 3.0 port without an issue. But some works on USB 2.0 ports, some doesn't. If it's a h/w issue why some works on it?
USB Flash Drive Check:
