@rubba.chikin Try going to devmgmt.msc - Mice and other pointing devices.. Assumed you have iCUE installed at the moment, do you have anything there that's from Corsair? Right click on them - Properties - Events tab - Scroll down by the 'Information' box and check the Parent Device. Try disabling the ones from Corsair if you have any. Don't uninstall as they'll get installed back with the next boot. The actual mouse should have the Parent Device: USB - might vary.

I agree, they provide the worst customer support I've ever seen. Pointing fingers at Windows... It's the operating system, you operate your software on it so you should optimize and adapt your iCUE to Windows, :mad: Corsair :mad:! I do work in DevOps too, I know how hard it is to create a properly functioning software and to provide an at least acceptable level of support for it, especially for something that's used by tens of thousands of people with hundreds of kinds of issues, but acknowledging the bugs and the problems is the 1st step!!!!! Nevertheless, I have my issues fixed at the moment. I went to check, perhaps my firmwares are not up to date. Turns out they were, anyhow I decided to go ahead and force an update. The USB disconnect issue and the fans going up to 100% then down to 0% then back to normal issue disappeared. Surprise surprise instead of going up to 100% then to 0% then to normal, the fans just got stuck at 100%. I didn't want to do anything else to troubleshoot this as I was afraid of the USB issue coming back, but I couldn't bear the noise of the fans anymore so I just had to fix it. Tried everything from once again switching USB ports for the H100i Plat, changing the slot the AIO's fan cable is connected to, to switching off USB selective suspend and uninstalling all my fan monitor/control software, HWInfo64 and Asus AI Suite that I use to control the rest of the fans connected to my mobo. Nothing worked until I went and forced an update of the FW for the AIO once again. In the middle of the update my PC simply switched off, no blue death or anything just completely off. Upon restart I went back to iCUE, forced another update and at the moment, as I said, all issues are gone. Awaiting the next challange that Corsair throws at me for my money! I have no idea how this issue could just come out of nowhere as I did not update the FW, the last time was months before the issue appeared. I was already running the latest, I do check every week usually. @puglord I'm glad I decided not to buy their so called commander pro. Thanks to Asus for their awesome motherboards and their features. @rubba.chikin I've had issues with Corsair trying to take over my motherboard, rendering a few of it's functions useless. Disabling SDK and Plugins in the iCUE settings solved that issue for me. I hope that helps because as you said, why would MadCatz care that your Corsair AIO doesn't work properly. I'm just not sure why Corsair wouldn't care! @Sineira You can enable logging in iCUE settings then export them to a zip file. I hope you all get your issues resolved. Best of luck,

Hey... Is there any solution for this? Just started experiencing this issue. Only seem to appear if the 2 fans on the H100i Plat are ≤ 50% over 50% no problem, but please do not tell me that I should just have my fans ≥ 50% as this is not working as designed and what I paid for. I am sure this is Corsair/iCUE related as I can also hear the fans jump to 100% then to 0% then back to where it was. Nothing else stops working just the H100i Plat. Also due to some cable management I have switched USB slots on the mobo and now I got 2x of the AIOs in iCUE.... Which was mentioned in this exact thread sometime in 2019 as I see. Please see: Apparently a bug still not resolved. The best thing in that is that I can control the pump only with the H100i Plat and the fans only with the H100i Plat (1) or the 2nd redundant AIO in iCUE. Before I had the issue of my whole PC freezing when iCUE was installed (blue death stopped straight after uninstalling iCUE), had issues with their K95 Plat XT... For all those issues there are threads going back years and they won't even acknowledge the issues..... God I hope my PSU from them won't catch on fire spontaneously.......... Any idea how to fix the broken Corsair software or just trash it?
