I can confirm this same behavour and error as the OP using a Gigabyte GA-990FXA-UD3 motherboard.
USB3.0 external drive (Seagate GoFlex) does not function in USB3.0 port, but does work in USB2 ports (at USB2 speeds). USB3 flash drives DO work in USB3 ports, but do not work at USB3.0 speeds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1050352 Title: [Gigabyte P55A-UD4] External USB 3.0 hard drive randomly disconnects and connects To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1050352/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
