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?
 
Solution
H. USB Connection Cable – Connect to your
computer to power the keyboard.
I. USB Secondary Power Cable – Connector that
provides additional power for lighting.

You want both cables in. If your computer crashes when you unplug the keyboard you could be yanking it out funny causing a power surge to the ports or you could just have an unstable system, a cheap power supply can cause issues.
