Bug Description
Binary package hint: pm-utils
Description: Ubuntu lucid (development branch)
Release: 10.04 (Installed from beta1)
pm-utils: Installed: 1.3.0-1
What I expect: To go in suspend mode
What happened: I see the "user locked" screen, I'm back on my session after entering my password
When I try to suspend the computer on 10.4 beta 2, I see the Login Screen after a few seconds.
Using dmesg -c I see some interesting lines >>>
pm_op(): usb_dev_
Device usb3 failed to suspend: error -2
Some devices failed to suspend <<<
I have fixed this issue by creating this script
/etc/pm/
#!/bin/sh
# Fix some issues with USB3
if [ "$1" = "suspend" ]
then
modprobe -r xhci
fi
if [ "$1" = "resume" ]
then
modprobe xhci
fi
Please note that this script load "xhci" even if not necessary.

I have an HP 8540w, people seams to have similar problems on the Asus N61J Laptop (and probably some other laptops with USB3 ports)

I have a Fujitsu SH760, and this issue also affects me. Removing the xhci module allows the suspend to happen, so this is definitely the culprit. Details of my USB3 controller (from lspci -v) are:
