You have been subscribed to a public bug: Issue: External USB3 drive (Seagate GoFlex 3TB) fails to mount, but is initially recognized by the kernel. See attached CurrentDmesg.txt for error. External drive formatted as ext4. Same unit works as expected on USB2 ports.
Expected behaviour: I expect my external USB3 drive to be recognized by the OS when plugged into a USB3 port, AND I expect it to operate at USB3 speeds. OS details: Ubuntu 3.13.0-24.46-generic 3.13.9 Description: Linux Mint 17 Qiana Release: 17 Motherboard details: Gigabyte GA-990FXA-UD3 motherboard -rev. 4.0 -BIOS version F2 (latest at time of writing) -USB controller - VIA VL805 "Support various Linux kernels": http://www.via-labs.com/en/products/vl805/index.jsp UEFI/BIOS set to enable legacy USB support and both XHCI and EHCI handoff to OS (enabling or disabling these has no effect). IOMMU enabled or disabled has no effect. Hardware IOMMU enabled (I think) with kernel boot parameters "iommu=pt iommu=1" modified in "/etc/default/grub".
