K100 keyboard disappears from iCue

[Parksie]

Having a problem with my new k100 keyboard disappearing randomly from iCue. Sometimes goes straight away and others it’ll stay for hours. If I then unplug it and plug it back in it’ll show for a split second then disappear again. I’ve gone through the usb devices and ports etc in device manager and made sure they aren’t allowed to sleep and gone into power to disable the usb sleep options in there, no joy. I’ve done a clean install of the latest iCue, this doesn’t help. I’ve tried it in all the USB ports on the rear and front of my case (all a mix of 3.2 gen 1 and 2) to no avail. I’ve even tried switching legacy on and off for the the USB ports in the bios, nothing is working. Come on Corsair get it together, I’ve spent a small fortune on your products and the least I expect is for them to work together?!?

Ok, I’ve now tried a clean install of Win11 and 10 which still hasn’t helped. I thought it might be armoury crate but installed iCue first so armoury crate wasn’t even there and it still did the same.

If it’s doing this with every USB port, there is a definite chance there is a problem with the KB’s usb wire(s) or connectors. This is not a common problem except when trying to use KVM switches and it doesn’t seem like that is in play. I would start a support ticket with Corsair or if you have easy exchange options with the vendor, go ahead and swap it.
