Are you sure that the USB drivers are loading properly??? As I have run both Logitech Mouseman Cordless Optical and the Cordless MX-700 mice without problems. Without the USB and Hid (Human interface Device) drivers loaded, you will not be able to use the mouse. (I'm running the MX-700 on the USB port as I write this message) You should see something like this when you run lsmod from the command line. keybdev 2912 0 (unused) mousedev 5428 1 hid 21892 0 (unused) input 5792 0 [keybdev mousedev hid] ehci-hcd 19784 0 (unused) usb-uhci 25996 0 (unused) usbcore 78272 1 [hid ehci-hcd usb-uhci] If you don't see anything in relation to the 'usbcore' stuff, then it may be likely that the USB ports may be disabled in the BIOS. Just go into the BIOS and enable the USB ports. You should see it somewhere in the 'Intergrated Peripherals' section if you BIOS has it.
