    How to determine if USB ports are 1.1 or 2.0


    I'm interested in buying a USB flash drive that's compatible with USB 1.1/2.0 and I want to know if it's compatible with the ones on my laptop.

    I attached a screenshot of the USB controllers listed in Device Manager.

    Can it be assumed that the spec's for the laptop show the number of usb 2.0 ports or is it in the details
    that the OP posted?

    /*EDIT */
    Never mind my original question :) Is it from Wikipedia?? Or Inspiron 1525 spec?

    Any flash drive you buy will be compatible with your machine. Even a USB 3.0 flash is backwards compatible and would work (but not at 3.0 speeds)
