How to tell what version USB (2.0 vs 1.1) my G4 has?

Hi Christopher,

Check out your ibook G4 model's specs on EveryMac.com found @:

hope that helps some,

Any Mac before the G5 with a built in USB port is 1.1.

Hi Kurt,

I looked on everymac and they list a number of the ibook G4's as having 2.0 either original or optional. Did I misread this?

best regards,

D'oh! No, you are correct, littleshoulders. Any tower Mac before the G5s were USB 1.1, but the laptops continued to use G4 CPUs for a while after the introduction of the G5 processor. So there are a a few iBooks that have USB 2 ports with a G4 CPU.

Thanks for the correction and sorry for the confusion on my part.

Hi again Kurt,

I've never used the iBook so I only had the everymac specs to go on. Sure is a bit confusing))).

I guess we should have known from the "Speed" that is listed in Christophers Profiler though. If the speed is 12Mbps then it would have to be 1.1 usb wouldn't it? I didn't catch that the first time I read the Profiler specs that Christopher posted. 2.0 usb is much higher isn't it?

best,

Hi littleshoulders,

Yes, 12Mbits/s is the top end for USB 1.1. USB 2 is 480 Mbits/s.

Christopher,

Yes, I'm sure that means that you have a 2.0 usb port on the iBook if Profiler is showing an entry for a port with a speed of up to 480.

I'm not sure why you are showing 4 usb entries in your Profiler though. Perhaps this has something to do with the optional 2.0 usb port mentioned in the EveryMac.com specs for some of the iBooks. As I said above to Kurt, I have never owned an iBook so I'm not that familiar with their configurations.

You did not post back with your exact model of iBook. This may help explain why you are seeing this. Did you have a chance to find your model iBook in the EveryMac.com listings and have a look at its specs there?
