[James Brierley <1072234@xxxxxxxxxxxxxxxxxx>]

The steps in the previous comment didn't work either. It seems that
autosuspend still occurs for individual devices even when usbcore is
told not to do it. I don't know enough about the internals of the Linux
kernel to know if this is intended behaviour.

I've tried manually adding every USB device to /etc/sysfs.conf, and I'll
see if that improves matters, but suffice it to say that my hopes aren't
high.

The only (possibly) helpful thing I've noticed is that whenever I
restart sysfsutils when the mouse has stopped responding, it comes back
to life. I don't know what this could mean.

Title:
  050d:0017 Bluetooth mouse randomly disconnects

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Since upgrading to Quantal, my Belkin bluetooth mouse disconnects
  sporadically from my computer. Sometimes this will happen several
  times a day, at other times it will stay connected for almost the
  entire day without a problem.

  After the connection is dropped, Bluetooth seems to become
  unresponsive. Generally unplugging and replugging the USB adapter is
  necessary to return it to a usable state.

  It was extremely reliable under Precise.
