Any news on this? I have the exact same problem as you did, have tried everything, but the damn driver keeps coming back.
I came home today to my computer at the bios screen. Every reboot failed citing CorsairVbusDriver.sys. Did a system restore to 3 days ago. Got to desktop, everything seemed fine. BSOD 5 mins later, system crashed again citing CorsairVbusDriver.sys.
