[EN] USB 3.0 won't mount external HD [Solved]

[clubex]

I've installed a known good USB 3.0 PCie card but an external USB 3.0  HD doesn't mount when it's plugged into the card's USB 3.0 ports. But it mounts when it's plugged into a USB 2.0 port.

lspci | grep "USB 3.0"

Code: [Select]


03:00.0 USB controller: VIA Technologies, Inc. VL80x xHCI USB 3.0 Controller (rev 03)

lsusb | grep "3.0"

Code: [Select]


Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

dmesg | egrep "xhci|usb 3"

Code: [Select]

NB: in the "xhci|usb 3" code there is NO mention of a Super Speed (USB 3.0) device which is what I would have expected.

The correct modules seem to be loaded (although I have no previous experience of USB 3 so I could be wrong).
lsmod | grep xhci

Code: [Select]


xhci_hcd               70535  0
usbcore               129729  6 usb_storage,ohci_hcd,ehci_hcd,ehci_pci,usbhid,xhci_hcd

I've even tried adding pci=nomsi to Grub thinking it might be a interrupt issue to no effect.

Can anyone help me get the external USB 3.0 card working/HD mounted?

My solution:
In /etc/modprobe.d/blacklist.conf add
blacklist uas
blacklist xhci

as root do
rmmod xhci_hcd
modprobe xhci_hcd

It worked.
