A:AnswerNo sadly this keyboard is not hot-swappable, however it is possible to switch out from reds to blue switches but it would require desoldering and taking out the stock switch h and soldering in the new switch.
A:AnswerYou only have to have one usb plugged into the computer(the one with the keyboard on it) to use the keyboard. The purpose of the other usb is to be used as a pass-through for devices you plug into the usb on the top of the top of the keyboard.
A:AnswerHey man, I'm a bit late but I also have this problem.
Is your keyboard connected directly in your PC? Is it going through any USB switches, or USB hubs?
