What are the 2 usb ports for on the Corsair rgb keyboard i plug one of them in and the keyboard works no problem then plug the other one in and windows tells me that it does not recognize it. also my keyboard never works upon starting up the bios. i don't know what to do about that. I get another keyboard and it works fine then when im in the bios my original keyboard works fine. my mouse just starts acting up when im actually in the bios. Also when i unplug my keyboard sometimes my computer will crash. does any one have answers for all of these questions?
