So I have been trying to find information about USB 3.0 but couldn't find much that made sense to me. I know its a faster USB version than 2.0. My questions are: Can you plug in 1.0, 1.1, or 2.0 USB hardware into these 3.0 ports? and If I have an external enclosure for a hard drive, can I just get a USB 3.0 wire and use it with the enclosure? And lastly, how do I know what version of USB my hardware is? I searched the forums but couldn't find anything on this. Thanks in advance for your input. :busy:

USB 3.0 is fully compatible with USB 2.0, 1.1, and 1.0 standards, though it will be bottleneced-you plug a 1.1 device into a USB 3 slot will run at 1.1 speeds. though, the problem your likely to have is driver problems-devices old enough to have 1.0 and 1.1 may not have drivers for modern Operating systems and may cause conflicts there. and yes, you can use a 3.0 wire with your external enclosure with no problem.
