USB 2.0 port devices are under 3.0 stack and controller. Now if I RESTART my notebook everything stays the same.
and the 3.0 Stack stops working and almost always the 3.0 ports stop workingĪll together. I manually sleep my notebook, after waking up Windows reinstalls USB 3.0 Drivers and uses the Intel Enhanced USB Controller (USB 2.0 Stack) even if devices are connected to 3.0 ports. For fast resume times, long standby and similar hybrid sleep state. Now Asus has a program called Instant On. Also the Power Management Tab is missing from the Host controller and xHCI Root Hub. USB 3.0 eXtensible Host Controller (100-Microsoft). I noticed slow transfer rates on USB 3.0 ports and MAINLY that in Device Manager that EVERYTHING connected to my only 2.0 port shows ups under USB Root Hub (xHCI) located on Intel GB, Kingston 8 GB DDR3 (2x 4 GB) 1600 MHz Dual Channel. Windows 8.1 Pro (圆4) and constant problems with USB 3.0! I have an Asus K55A notebook, Intel 7 Series/C216 Chipset, HM76 running Core i3-3110M, Intel HD 4000 iGPU.
