to help with installing, ive tried to put my iatkos v7 onto 8gb usb pen.

I used disk utility to partition and format the pen (journaled, 1partition, mbr) and used restore and selected the iso as source and pen as destination.

I can boot with the usb pen, however when the "press ok to continue" screen appears, the touchpad does not work? can i fix this or must i use a usb mouse
