o keep it short, my Corsair K70 Core keyboard wont start with the rest of the other devices.
I have to restart Signal, disable and enable the keyboard again or unplug it and plug it in again, any of the three and then the effects start.
Im not running iCue, I tried with iCue, update firmware, delaying start and nothing, I have to manually disable and enable to the effects take place and is really tedious.
Bro I think I found it, with you trying the power cut, and having the same fix as me I thought “it must be something power related, maybe the usb” tried changing to another usb port and that worked, simple as that. I dont know if the port is faulty or maybe has something to do with the order everything is conected in the back, i dont know, try if it work for you too
