Welcome to my world, It's been almost a year like that, each time I turn on my computer, need to disconect and connect 3-4 times until it wants to turn on.
I left this message in the Rapid thread since seems this issue has been addressed in that model, but Cooler Master don't give a :) about the QuickFire TK as far as I can see.
Good luck on that, and hope you get an answer cause I need it too... I'm already saving for a Logitech G610... because this doesn't seem to be reaching any point at all and I'm really frustrated about this issue having it EVERY SINGLE DAY. I bought a mechanical because they are stronger than regular ones with heavy usage, and mine has lasted perfectly until today, however I'm now stuck because of a software/drivers issue... after 2 years of having it, so basically it's lasting the same period as a regular keyboard, with the difference it cost 80â‚¬ more than a regular membrane one...
BTW: Seems CM guys are more active in its reddit than here: https://www.reddit.com/r/coolermaster/comments/4bnz3a/quickfire_tk_unrecognized_on_windows_10/?st=itq0mvee&sh=eb33a9c0
Gonna try myself there and see If I can get this fixed... Seems a massive issue though, just search for TK windows 10 usb device and it returns a ton of similar issues.
