Powerbook USB Ports Not Working As USB2.0?

    I've got a 15" Powerbook G4, 1.67ghz, with apparently a USB issue. I was trying to backup my HDD via an internal in an enclosure and noticed extremely slow speeds. Checking my Sys. Profiler, it looks like my USB ports are only reading as USB 1.1, though they should be 2.0. Both USB Bus Speeds say "Up to 12Mb/sec"...

    What's going on here and how do I fix it?

    EDIT: Above issue solved, but question below still stands...

    And a slightly off-topic question. The enclosure I bought for my replacement HDD came with a mini-USB to USB Y-cable. It's supposed to be USB 2.0, but I had thought that all USB 2.0 cables had the little "+" sign above the circle in the symbol...and this doesn't. Do they all not? Obviously I have no way of checking whether the cable is actually pulling USB 2.0 speeds...

    Thanks for the help!
