I'm having an issue getting my Logitech MX1000 USB mouse working under linux since my recent 2.6.14 kernel upgrade.

This is the output of dmesg for the USB host controller...

And this is the output of lspci...

The SiS chipset, and appropriate USB modules have been loaded into the kernel, everything seems to be set correctly, I just can't get it to recognize the mouse on bootup.

Any help would be appreciated.
Thanks
