No mac has USb 2 on it (except power macs with third party cards). its a different hardware standard, and not one currently supported by apple at all. USb 2 devices will work at USb 1 speeds. Don't expect USb 2 until firewire 2 comes out at twice the speed of USb 2.Originally posted by maclamb
I just got an Iomega Portable CDRW drive and it says it will run at 4x if USB 1.1 and 20X if USB 2.0
Does the TiPB667/OS 10.2.3 support usb 2.0?
