I'm facing the same problem with both my laptop (Lenovo G500s) and Desktop (AMD FX 9590, Asus M5A 99FX). USB 3 hard drive doesn't work with USB 3 port, but any other combination works.
USB3 > USB3 = Doesn't work USB3 > USB2 = Works USB2 > USB3 = Works USB2 > USB2 = Works I never tried a USB 3.0 device before, right now I'm using Ubuntu 16.04 LTS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242321 Title: USB 3.0 Harddrive not recognised To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1242321/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
