Just wanted to let you guys know that my GCTP, with the original InstantAOL software (with no modification whatsoever) happily recognized a USB keyboard plugged into one of the rear usb ports!.
And the keyboard I've used is not a "standard" keyboard... it's a Silicon Graphics (SGI) USB keyboard which comes with a built-in PS/2 MOUSE PORT on the side. (So you plug the keyboard into the system's USB port, and plug a PS/2 mouse INTO the keyboard... very nice hehe :).
End of the story: both the USB keyboard and the PS/2 mouse (connected to the keyboard) are recognized and work 100% ok with the original InstantAOL software! There isn't even an annoying pop-up when you insert/remove the devices like in windows...
