Hi Phil 87, I have a K70 RGB which was on CUE 1 software for ages until I just purchased the Glaive mouse which required CUE2 to work. So I upgraded to CUE2 and the problems began like yours. At first boot all was fine, but as soon as you log off/change windows user/log back on, no hardware detected. I'm on Windows 7 pro x64 like you. My way around this at first was the same as you (exit CUE software from system tray then restart it - mouse and keyboard now show, until next reboot or logout etc anyway). After hours of testing, updating BIOS, USB drivers etc, nothing worked until I discovered a work around. Right click on the CUE software icon on desktop or start menu, compatibility tab, tick "Run this program in compatibility mode for" and select "Winows 7" from the drop down list! Stupid huh but it seems to work. If you have more than one user on your PC, use the "Change settings for all users" option and set Windows 7. Log off, logon, switch users, reboot all work for me now so give it a go. Whilst I was troubleshooting this for 2 days I logged a ticket with Corsair - after 3 days they replied with this: "Sorry about the delay. CUE is designed around Windows 10 primarily. Although, this is seems to be a unique situation. Can I confirm you have the latest motherboard chipset and USB drivers installed for your motherboard? Also try disabling "USB selective suspend setting" in Window's Power Option menu." My PC is all up to date, but I haven't tried the selective suspend setting yet. So it looks like us Windows 7 users may be getting neglected as time goes on and will be forced to upgrade to Windows 10 real soon, which I'm reluctant to do just yet. Anyway, hope this helps anyone with same symptoms, would be good to know if this works for others or not. Good luck!
