Hi list,
I have a Toshiba Canvio external HD drive attached via USB 3.0 to an
Asus Fatality board, but the two do not quite get along. Sometimes
forever, sometimes just for about 20 minutes, all I get is (in
/var/log/messages and similarly in dmesg):
Sep 24 23:32:19 calcox kernel: [19729.969142] usb 3-8: reset high-speed
USB device number 3 using xhci_hcd

xHCI xhci_drop_endpoint called with disabled ep f70fbb6c
every 10-20 seconds.
When I detach and re-attach the usb cable, I get a reasonable connection
sequence:

Sometimes, it works after that, sometimes it doesn't.
If I remove the power from the external device, the messages go on.
Apparently, USB power is enough to try to establish a connection.
If I connect the drive to a USB 2.0 port, the problem persists.
lspci yields the relevant entry

I have searched around a bit, and most solutions revolve around the uas
(USB-attached SCSI) module, but that is not loaded, according to lsmod.
Where can I look further?

Have fun,
