    Suddenly my USB 3.0 ports stopped recognizing my hard drives... they still work in USB 2.0 but obviously they're not as fast now. When I plug one drive into either USB 3.0 it lights up but doesn't spin up, so I don't think the ports are completely busted. I think I installed the latest firmware and drivers but nothing was fixed, any ideas? My laptop is a P151HM1

    Something like this kept happening to my Asus N53 at a point. The day before it would be functioning, and upon plugging in a USB 3.0 HDD the next day, it would simply light up blue without doing anything or being recognized automatically. I would go into device manager and disable the USB 3.0 root hub underneath USB controllers then re enable it for it to start working again.

    restarting the root hub fixed it thanks!
