usbdev4.1_ep00: PM: suspend 0->1, parent usb4 already 2

Upon trying to use a USB device on this system (a DVD writer), it has become apparent that there are further problems. Even on a clean boot where no suspend/resume has taken place, the device doesn't work properly:

Can you try unloading ehci_hcd module and see if that changes anything?

I unloaded ehci_hcd, then did a suspend/resume cycle, and I still got the
messages.

Thanks for reporting this bug. To make any progress with it, some more information will be needed. Please add (by commenting on the bug) to the bug report the output of the following commands: 'uname -a' 'sudo lspci -vvn' 'sudo dmidecode'. It would also be helpful if you could try to hibernate/suspend and after that fails, restart your system and attach /var/log/kern.log.0 as well. Thanks again for your contribution.

There's no further info needed. Basically this is just new output from the USB core for sanity checks on the pm code.

Not sure if stopping this output is ideal, but we'll try to clean it up.

Confirmed bugs need to be assigned to ubuntu-kernel-team.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

This went away with one upgrade or another. Now I only get over-current messages instead of these.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
