I have read mixed messages on whether I can use things like USB wireless dongles in a 3.0 port. I have read that the 3.0 can mess with the receiving of the radio signal vs a 2.0 port. I am thinking of getting a floppy bay SUB panel that is just 2.0 ports because I have all 3.0 on my motherboard and my case has two 3.0 ports but no 2.0. I am specifically concerned about wireless devices like keyboard/mouse combo and gamepads. I am having a hard time finding just 2.0 ports. I have found some that are 2.0 and 3.0 but to use the 3.0 I would then need a splitter to tie into the case ports. Should I stick with just 2.0 ports or am I worrying about nothing.
