I'm a Ubuntu 10.04 user. What's the fastest way to tell if the two USB ports on my computer support USB 3.0? I'm not sure if they're 2.0 or 3.0, and I need to know. Thanks!
First be sure that your motherboard SAYS "Supports USB 3.0"
Then you can for example go to the terminal and type
lsusb and it will show the version of the usb.
Another can be
lshw but it shows a lot of info
If you want super full info then do
sudo lsusb -v this should give you whole information about all ports and anything connected to any usb port.
