I have a USB 3.0 hard disk which has always been working on my desktop with an XHCI.
Now I just bought a notebook with an XHCI (something with Intel's Ivy Bridge setup). The first time I plug the hard disk in its 3.0 port it is detected and working.
A few hours later I try to connect it again, but seems that the notebook just ignored it! The light on the hard disk didn't blink as usual (instead it is hold at
I then tested it with my desktop again and it is working perfectly. It gets trickier when I plug it in the USB 2.0 port of that notebook it is detected and working perfectly (despite the slower speed).
Then I try to plug in an USB 2.0 USB flash drive to that USB 3.0 port, and it is detected (of course as USB 2.0).
So, there are two USB 3.0 ports on my notebook's XHCI. Both of them are not working with my hard disk but working perfectly fine with my USB 2.0 UFD. What's wrong with it?
When I plug in the hard disk, device manager doesn't change. I've tried re-installing the driver for the XHCI, but it changes nothing. Had I broke the USB 3.0-specific pins of both USB 3.0 ports?
