Recently ordered a Tt Challenger Pro from Amazon for my build, popped it out the box all excited and whatnot, and plugged in the USB only to have it not register with my computer in any of the USB ports. Initially thought it was an issue on my end and tried plugging in other USB devices (headphones, mouse). They registered immediately, so I know it isn't that. However, for the keyboard, no pop-ups or bells dinged, informing me that the item is unrecognized or anything, just silence and a lovely--albeit now rendered useless--keyboard. Would greatly appreciate support/tech getting back to me on the matter in a timely fashion.
