Re: 3.0 and 2.0 USB: Desktop > flash drive > laptop
You can plug 3.0 devices into 2.0 ports. 3.0 is backwards compatible. You don't need a flash drive to move files from the 3.0 hard drive to the laptop. The 3.0 device will just operate at 2.0 speeds when plugged into a 2.0 port, and a 2.0 device plugged into a 3.0 port will also only operate at 2.0 speeds.
