    My guess is no.
    If it did you would see something more like the following:

    USB 3.0 Hi-Speed Bus:

    Host Controller Location: Built-in USB
    Host Controller Driver: AppleUSBXHCI
    PCI Device ID: 0x1e31
    PCI Revision ID: 0x0004
    PCI Vendor ID: 0x8086
    Bus Number: 0x0a

    USB 2.0 has 480 Mb/s transfer rate.
    So it is Probably USB 2.0.

    But it would be easier to tell if you gave us the release date of your iMac ;)

    Hi-Speed USB = USB 2
    SuperSpeed USB = USB 3

    So no, that specification you listed shows USB 2

    It is USB2. Thanks for the replies.

    Will a USB3 cable or flash drive also fit into a USB2 port on a Mac that doesn't have USB3?

    Yes, it is backwards compatible, but you will revive USB2 speeds, not 3.

    I have a couple of USB 3 backup disks, and they work fine on a 2008 iMac with usb 2.0...
