When I recieved a CM Storm Keyboard, it came defective. Some of the keys did work, until I booted up into the OS I was installing. When I received a second keyboard it worked until I plugged it in into a different machine I assembled for my friend and worked until he shut it off again. Then I plugged it into his again and didnt work. Then I assumed it was just his computer until I plugged it into everything with a USB port and never turned back on. Was this a coincidence that both these keyboards were defective or something else?
