I am buying a Dell Inspiron 15z. It has 4 USB 3.0 ports, but I have two 8GB USB 2.0 flash drives. Will those work?

    Yes but you will only get USB 2.0 speeds of up to 480Mbits/s or 60 megabytes a second.

    As far as I know, it's usable, though your USB drive wouldn't get the speed advantage

    Sure. They are backwards-compatible, and will work just fine!

    Yes, USB 3.0 is backwards compatible with previous versions. See http://en.wikipedia.org/wiki/USB_3.0#Implementation_differences_compared_to_USB_2.0 .

      I am a DJ. I just purchased an Audio Interface (Traktor Audio 2). I can't get it to work at all with my USB 3.0 ports; I have Windows 7.I have been on the phone with "Native Intruments", the manufacturer off and on and one of their techs finally fessed up and told me that they have been having serious issues with their current devices working with Windows 3.0.

      So as you can see 3.0 is not entirely backwards compatible. If you have a fix besides converting all of my ports to 2.0 speed I would thank you! I might even try that if I can be assured it wouldn't cause more issues...

    Yes, you can but data reading and transferring would be at the USB 2.0 slower speed. You have to use a USB 3.0 devices in order to enjoy the higher 3.0 speed.

    USB 2 will work in usb 3 as it is backwards compatible

    Yes you can use your USB 2.0 on USB 3.0 ports , they will work as they should but you may receive the notification that "This device can perform faster"

    Yes. USB 3.0 ports are backward compatible with USB 2.0 devices.
