OK, just a quick note, I got the USB mouse to work.. I just had to do a
Code:
sudo modprobe uhci_hcd
And it started working again.

I've read on a couple of discussions that it may be related to some bug in the ACPI modules, and that for some people, the mouse will stop working every now and then for no apparent reason and won't start again until they modprobe it to life once more. These discussions were talking about pre-test9 kernels, so that may have been fixed.. I'll let you know if it happens to me.

Have you tried modprobing around your usb devices to see if maybe that perks your UPS thing to life/ Worked for me with the mouse, at least, no need for additional recompiles, even.

Now that I've gotten the mouse working once more, everything else seems to be going pretty smoothly with 2.6.0-test9. I've run into a few bugs bringing up some windows programs under WINE that seemed to run pretty flawlessly before, but those are minor concerns, none of my WINE programs are critical. Haven't tried out the CD burner yet, I'm downloading the latest Knoppix ISO and will burn it once it finishes, I figure burning a bootable image is a fair test of wether the burner works fine with the new kernel.
