I'm typing this on my old Logitech keyboard. I have had my huntsman v2 for a few months now with no issues. Then it stopped showing up in synapse but worked overall still. Today I decided to try and get it to show in synapse again, did the uninstall and reinstall with the drivers and it worked... for about 5 seconds then just stopped responding but was still lighting up and showing up in synapse. I followed the youtube video for how to "fix" this and it is now in demo mode. Tried to follow the video for how to get it out of demo mode, and it did nothing. I have been fighting with it for about an hour or so now and I'm very frustrated and confused. It shows in my settings under mice and keyboards but not in the device manager under keyboards, only under HID. What can I do to fix this?
