Can all of you confirm which version of iCUE and Windows you are on? Just to confirm, the primary issue you all are having is that ST100 is not showing in iCUE after performing the firmware update?

Corsair headset sound issues after an iCUE software update Fix Corsair headset sound issues after an iCUE software update

However, I can't solely place a fix on that alone, because I also tweaked other settings at the behest of Corsair support. They are as follows: I cue.firmware.update.controller: "ST100RGB" FW update has been failed. From "Primary FW: 0.02.91; Secondary FW: 0.02.91; Bootloader FW: 0.01" to "Secondary: Application: 0.4.106" Not that i am aware of. Most CUE related issues e.g. Device not detected, device disconnecting, effects not running are usually resolved when the device is plugged into a AMD/Intel controlled port rather than a third party one.

I'm still having trouble with power issues though. It seems to be failing with code 1167 in the logs. It'll shut down and then continuously try to start up again but never make a good connection. Restart windows 10 in safe mode, open up icue and install the firmware. It took like 20 minutes on mine to finish but it worked. I cue.hid_device_detector: "\\\\?\\hid#vid_1b1c&pid_0a34#7&1d49b690&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}" closed. Me too! I tried every USB port on my PC, and nothing works. Works fine for every other device in iCUE, except this. This product is problematic, and unfortunately...Corsair support just goes immediately to replacement rather than passing on our information to the experts. We'll just have to do the best we can here.

If so, the issue may be caused by the latest iCUE software update coming into conflict with your Windows build. You can try one of the following fixes below.

two USB 3.1 inputs

My next instinct was well maybe something on Windows 10 is conflicting with the USB. So I went into Device Manager, found the ST100 and Uninstalled its Drivers manually, uninstalled ICUE and rebooted my PC, reinstalled ICUE and plugged in the ST100. This time the ST100 did not auto detect even by Windows and the lights failed to come on. I talked with support but wasn't able to fix the issue. I have the most updated BIOS and chipset drivers for my mobo, windows claims USB controller drivers are the best. I've enabled USB legacy support, disabled XHCI handoff, disabled USB selective suspend. Still having the issue though. Just completely cuts out and error codes 1167.
