    I have a PC that's 4 or 5 years old. It has two USB ports on the rear that I use with a digital camera.

    How can I determine which version of USB this PC has on it? USB 1 or USB 2?

    Thanks, Steve

    4 or 5 years old will be USB 1.0/1.1. USB 2.0 will offer faster transfer speeds if the device attached to it is USB 2.0, ie you're camera.

    You can buy a PCI USB add-in card if you wish to have USB 2.0 ports.

    Thanks for the info. I got the PC from a guy who got it from a guy who got it from a guy . . . . So the 4 or 5 year age is the guess of the last guy in that chain. So I was hoping for a way to more definitively determine which version of USB the PC has on it before buying an external disk drive that is spec'ed as requiring USB 2.

    Is there a driver I can look at? Or somewhere in the BIOS? (I looked around in the BIOS but found no mention of USB version.) It uses the Intel 82801BA/BAM USB Universal Host Controller -- does that chip set give an indication of USB version? Is there a snippet of code I can run that will indicate USB version?

    Thanks again, Steve

    "Intel 82801BA/BAM USB Universal Host Controller"

    USB 2.0 is label "Enhanced" USB controller in Device Manager, and the 82801 chipset only came equiped with USB 1.1 as USB 2.0 is only a recent revision.
