Hi, today I posted some data within a Doc and some observation to the support [Ticket Id : 627957]. It may be an USB driver problem (don't know if "Corsair Bus" system driver or the HID "Corsair" one). It seems something weird happens when refreshin USB chain events (and Steam is launched too).
Updated 12 Oct: As suggested from the support I uninstalled CUE, used CCLeaner to remove possible residual registry garbage, and restarted: hopefully drivers are not in the game anymore now. Behaviour changed pehaps for some time but Steam /Games now freeze anyway on removing and reinserting a controller. Perhaps a firmware 30.06 problem with USB managment is there afterall. I'm starting to be very unhappy: please let me know if you have any advance in discovering what it's really happening, even if a fix is still not available! If after about 10 days Valve and Corsair still doesn't have any advancement...my hope starts to fade away.
