[Bug 50838] USB dead after unplugging default USB audio adapter

[Aleksander Blomskøld]

Public bug reported:

Binary package hint: gnome-volume-manager

I'm having a problem with the USB-ports being dead after unplugging my
USB audio adapter. It seems like gnome-volume-manager is blocking the
USB ports. This is always reproducable for me, and for a friend of mine
which has tested on a different computer with a different USB-audio
adapter. We're both using laptops with Ubuntu Dapper installed.

Here are my steps to reproduce and the syslog-messages I get:
* Unplugging the audio-adapter
Jun 24 17:38:05 localhost kernel: [17214132.772000] usb 1-1: USB disconnect, address 3

The USB-mouse is still working.

* Unplugging the USB-mouse

* Plugging in the USB-mouse
USB-mouse not working, not even getting power. No new information in syslog.

* Chaning the device for gnome-volume-manager to control from the USB-adapter to my sound card on the motherboard of my laptop:
Jun 24 17:39:13 localhost kernel: [17214200.396000] usb 1-2: USB disconnect, address 4
Jun 24 17:39:13 localhost kernel: [17214201.052000] usb 1-2: new low speed USB device using uhci_hcd and address 5
Jun 24 17:39:14 localhost kernel: [17214201.248000] input: Logitech USB-PS/2 Optical Mouse as /class/input/input4
Jun 24 17:39:14 localhost kernel: [17214201.248000] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1d.0-2

The mouse is now working properly.
