Dear Remy And Matt,
I just got a new Windows 7 desktop with 2 x (2.0) USB ports and 2 x (3.0) USB ports. I was wondering if I can use my older USB devices on my USB (3.0) ports ? and I’m talking as far back as (1.0 or 1.5) USB devices.

Remy’s Reply: A really good question. I actually ran into this question myself with a clients PC. So anyways to answer your question you can indeed use older USB devices on the USB (3.0) ports. But it won’t run at the elevated speed. Unless you are using a USB (3.0) device with your USB (3.0) ports.
Your computer will actually give you a pop-up message saying. That your device will not run at peek speed. Because it is not USB (3.0) device supported.
Matt’s Reply: When it comes to USB 2.0 and USB 3.0 ports there is, just like many devices these days, the ability to run both newer and older tech in either port. Let me explain.
If you attempt to use a USB 2.0 device on a USB 3.0 port then the device will take advantage of the newer tech and transfer data slightly faster than normal, but not by much. Although, if you attempt to run a USB 3.0 device on a USB 2.0 port then it will be compatible, but it won’t run at peek performance, as the older port doesn’t have the required tech built-in to take advantage of the newer device.
This is the same with all backwards compatible technology. Just ask the gamers out there.
