Hello everyone I have a Lenovo y510p laptop and I have an issue with Windows 8.1, I have 2 External Hard Drives which are also USB 3.0 I remember problems started when I plugged in a generic chinese USB 3.0 hub. Now my laptop won't recognize my external hard drives like at all, won't even show from Device manager nor Disk management. I tried plugging in the drives to a separate computer to check if it's something with the cables or the drives, but the drives work fine on a different computer. My USB ports still recognize a USB 2.0 External hard drive, but not USB 3.0, I tried all ports and my laptop just won't recognize my USB 3.0 hard drives, just the USB 2.0 one. This is very frustrating and I've looked everywhere without a solution so far, I'm pretty sure this has something to do with the Drivers but I try to click uninstall or Update to all USB devices and it just won't do the trick. If anyone around here has a clue what might be causing this issue and if there's a way to fix it I'd really appreciate any help I can get.
