Dear friends,
first of all, I am sorry for my english. And here is my problem i am trying to solve for several days...
I have two PCs with the same hardware configuration, both with W8.1 (actually now with W10, but i come to that point).
On one of the PCs, USB 3.0 ports do not work. They work fine in bios. I can use mouse and keyboard normally using USB 2.0 and 3.0. In device manager I have eXtensible Host Controller with caution icon (you know - the exclamation thing).
So i started trying all the basic solutions which came to my mind:
- Updating drivers (chipset and intel managment engine only. usb 3.0 drivers are not provided by mb manufacturer)
- Updating bios to latest version (all usb stopped working)
- Tried disabling / enabling xHCI in bios as advised on other forums. Still no usb working.
- Tried disabling / enabling other usb features in bios with no luck.
- I downgraded bios verison (7 verisons down). USB 2.0 started working!
- I eved did clean install of windows. Still only USB 2.0 work.
- After some time, I was allowed to upgrade both PCs to W10. Still the same problem.
After a lot of forums and frustration, I foud out, that the problem is propably releated to USB Controller Extension.
I started comparing problematic Host Controller with the one, on second PC and I can see in device properties, that on PC, where USBs are working fine, eXtensible Host Controller is using ucx01000.sys and usbxhci.sys driver files. PC with "broken" USBs, is using usbxhci.sys only. I tried this - USB Controller Extension - Windows 8 Service - batcmd.com . But with no luck. And now I am stuck! I don't really know what to look for or where to look to find some advice. I hope you will be smarter than me.
Thank You.
