The new generation of skylake corresponding to the 100 chipset has brought many practical features, support DDR4 memory, sata-express, m.2 interface and so on. Yes, but ! The original EHCI master is also replaced by the XHCI master control. , what the hell is this?
I believe that some of the 100 series of users have been in the chip group have encountered this problem-when the Win7 system, the USB interface connected to the mouse/keyboard/U disk are all wasted ....
After the user after their own meticulous investigation, and finally well-behaved ♂ win8/win10 Good (Microsoft and Intel to each other smile ~ Cheers!!) --I believe many users are using this method to solve.
But some users are still accustomed to using the Win7 system, then today's small series to give you some tips, so you can in the 100 series chipset under the normal use of the Win7 system USB interface bar.
100 Series motherboard USB disk mount Win7 The mouse keyboard Why is it malfunctioning?
Skylake this generation chipset Intel replaces the EHCI master with the XHCI master , and the Windows 7 system native is not XHCI-driven, so the pit is dug out.
Win10 and Win8 are native with XHCI drivers, so users who install both systems do not have to worry about USB failure. In fact, Microsoft forced everyone to upgrade the small means just. And in recent days, Intel, AMD, Qualcomm are starting to stop supporting WIN10 systems from the next generation of CPUs . What do you think?
What the hell are EHCI and XHCI?
XHCI (extensible host Controller Interface) Extensible Host Controller Interface, is the USB host controller developed by Intel, the USB protocol of the 100 series chip is XHCI master, which is oriented to USB 3.0 standard, It is also compatible with devices under 2.0.
Prior to the Broadwell used before the EHCI main control, mainly to face the 2.0 standard. and the original Win7 system only EHCI drive without XHCI drive , so the consequence is ~ you know.
If you know that failure is due to the lack of drive, it is not good to install it? There must be a netizen who would say, "you idiot!" Please do not hurry to spray a small series ~ and first look at the following logical diagram.
See the awkward place where wood has? If it's that simple.
However, the mouse keyboard connected through the PS/2 can work , but the new platform on the use of PS/2 interface of the user is not too much? And even if you are the mouse keyboard is the PS/2 interface, the motherboard on the USB interface is still malfunctioning.
But if there is a PS/2 mouse, the problem is solved a lot, after installing the WIN7 system directly login to the motherboard brand's official website, to find the corresponding motherboard driver download and install it.
