Replacing USB 1.1 with USB 2.0 on G4 iMac - Current Mac Hardware Discussions on AppleInsider Forums Toggle navigation All Forums Recent Posts Sign In Replacing USB 1.1 with USB 2.0 on G4 iMac satchmo Posted: March 27, 2006 2:57PM in Current Mac Hardware edited January 2014 Dumb question perhaps but is this even possible? Not sure how it all hooks up but can one simply replace the ports or is it a bigger issue that involves the motherboard?
