    Do I *really* have USB 2.0?
    Hi -- I'm trying to hook up an external HD by USB on my eMac 1Ghz, Power PC G4.

    It's been SLOW SLOW SLOW! (.6 Mb/s rates)

    The System profiler tells me I'm running USB 2.0 (with speeds of "Up to 12 Mb/sec"). But I've read elsewhere that Apple's "USB 2.0" may really be "USB 1.1."

    Anyone know?

    My girlfriend's Intel MacBook also says "USB 2.0" but claims speeds of up to "400 Mb/sec". The transfer rate for her USB was 1.7 Mb/s.

    Thanks

    Specs:
    iMac late 2007 10.11.b4, iMac 2008 10.10.5, Macbook2007 10.7.5, Mac Mini 10.7.5, iPhone 3GS Note 8!!
    Apple does not use FAKE USB 2.0. But something is wrong as 12Mb/sec is not 2.0 but 1.1.

    Will check around and see what I can find.

    There are 2 different runs of 1Ghz eMacs. A 2003 model with 3 USB 1.1 ports and a 2004 model with USB 2.0 ports.

    What OS is on the system?

    2003 Model.

    2004 model.

    Unfortunately you have the USB 1.1 model. For confirmation, check your eMac specs at http://www.everymac.com

    There is a 1Ghz model of the 2004 Emac that has 2.0. I am pretty sure though he has the 2003 model which is 1.1.

    12 Mb/sec is USB 1.1. USB 2.0 transfer is rated at 480 Mb/sec. You have a USB 1.1 eMac. Sorry.
