I have a corsair K83, I'm connecting the dongle to my SHIELD TV, and sharing it to my PC via virtualhere.
I'm doing this because it's the only way I won't have issues with windows hotkeys when using moonlight/gamestream.
The problem I have is that when I "use" the device, sometimes it causes my computer to hang for a couple of minutes. It really does freeze altogether, meaning I can't connect via remote desktop or anything of the such. After that time passes it comes back and works normally. Heck I can even stop using and start using it again and it won't hang again until my PC has gone to sleep or rebooted.
