Comment 51 for bug 54273

I'm on Ubuntu Karmic 2.6.31-22-generic #60-Ubuntu SMP Thu May 27 00:22:23 UTC 2010 i686 GNU/Linux, on an Eee PC 1000H. Periodically and seemingly randomly, my internal bluetooth adapter will exhibit the above symptoms, and sytem logs will show messages along the lines of:

63.509374] usb 5-1: device descriptor read/64, error -110

The only modules loaded are usbhid and btusb.

I'm using Blueman to manage my bluetooth devices. The problem most usually occurs after I disable the adaptor, then re-enable it again with blueman's tray applet. No amount of fussing with services or modules or rebooting brings it back.

The only thing that appears to work consistently, so far is to power off the laptop, and remove the battery for a couple of seconds/minutes, plugging it back in and rebooting. I tried restarting dbus as well, but some rather nasty (unrelated) things happen after this, and I usually have to REISUB.
