Comment 7 for bug 572879

Hi same here on a Acer Aspire 9410z.

Suspend and Hibernate won't work, and by looking dmesg there is a problem with usb_dev_suspend.

[ 259.744267] pm_op(): usb_dev_suspend+0x0/0x20 returns -16
[ 259.744274] PM: Device usb1 failed to suspend: error -16
[ 259.744279] PM: Some devices failed to suspend

I have a Ali Corp. Video Camera hard plugged.

Suspend and Hibernate work fine on Ubuntu Karmic.
