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

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

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.
