I have been trying to get my usb mouse to work with the live cd with no luck. Nobody at the Gparted forums has any ideas, but there were several other people with the same problem. The only response was to buy a PS/2 mouse. I know it is built on top of Gentoo, of which I'm completely ignorant as far as commands. I looked at the files on the live cd, and there was a kernel option "doscsi" that was supposed to be critical in registering usb devices. I added that to the boot option in the grub menu with no luck. Xorg had all mouse types listed by default, with nothing commented out. Any ideas?
