Hi,
first: keep me posted, I'm not subscribed to this list.
When I connect an external USB 3.0 HDD, I see the following in my
logs:
[ 24.616996] usb 9-2: new SuperSpeed USB device number 2 using xhci_hcd

Without doing anything, after a few minutes, the logfile is spammed
with a LOT more "parent hub missing LPM exit latency info" lines, and the
device gets disconnected showing this (USB_DEBUG enabled).

Kernel driver in use: xhci_hcd
The drive is unuseable with USB 3.0, but works ok on any USB 2.0
controller. The filesystem on the HDD is not corrupted, and the HDD is
not faulty. Kernel 3.14.4 vanilla.
What can I do to get this to work?
Thanks, Heinz.
