Binary package hint: linux-source-2.6.20

The USB devices (mouse, printer) connected to my Toshiba Satellite M-40 running on Gutsy started to randomly stop working today. I've had Gutsy installed for just over a month now, and had been running Feisty for 6 months with no problems with either device -- no idea what caused this to stop working, although I did install several updates for Gutsy today.

I noticed this first with the mouse -- it is a Microsoft Standard Wireless Optical Mouse. Unplugging and then plugging back in does not help, even to a different port. The printer, a Samsung ML-1740 laser, also gets dropped. I managed to grab the outputs from lsusb before and after the failure, as well as dmesg and Xorg.0.log, will attach.

Again, I have had *no* USB problems with Ubuntu for seven months, and I have no idea what could have happened to trigger this.

The last few lines from dmesg could be helpful:
