I have lots of keyboards. But, I have one in particular that I really like. It's a brown switch back lit mechanical keyboard, but it keeps connecting and disconnecting. None of my other things plugged into my USB ports have any issues besides the keyboard. It works great for about 4 hours, then all of a sudden randomly disconnects/connects like crazy every 5 seconds or so until I disconnect it completely. Could it be a faulty keyboard, or something to do with my USB ports? I've tried messing with the USB power settings but made no difference. I've even tried downloading the keyboard program hoping it'll download some drivers, but still not working. Ahh... Tried googling but found nothing really apart from messing with USB settings which I've already done. Any idea? Thanks!
