I have run into many USB 3.0 problems across multiple devices and computers running Windows 8 Pro 64-bit. After many headaches and sleepless nights I think I have narrowed all the problems down to one thing in Device Manager: "Intel (R) USB 3.0 eXtensible Host Controller -0100 (Microsoft)”
The controllers (Multiple Computers) have had problems with all the Microsoft Drivers including the most resent: 6.2.9200.16548 3/1/2013
The problems:
- USB 3.0 External Optical Drives (labeled Windows 8 compatible) not recognized or continuously disconnecting/reconnecting with or without manufacturers drivers.
- USB 3.0 Flash drives running slow and/or disconnecting often with data corruption/loss
- USB 3.0 Flash drives not recognized
My solution: <Disabled> “Intel xHCI Mode” or “XHCI Pre-Boot Mode” in BIOS/Firmware
This solution Takes the "Intel (R) USB 3.0 eXtensible Host Controller -0100 (Microsoft)” out of Device Manager and eliminates all the problems stated above across multiple machines running Windows 8 Pro 64-bit.
However: This is not a fix.
The Intel USB 3.0 controllers on the machines seam to only run at 2.0 speeds. (Before they were also slow but much less functional, often not recognizing devices)
Non-Intel USB 3.0 controllers are fully functional at full USB 3.0 speeds. (Before they had limited or no function depending on the controller)
This appears to be a fix for non-Intel USB 3.0 controllers but what about the Intel controllers that take the lion’s share of USB 3.0 controllers on the market?
Dose Microsoft have a fix for "Intel (R) USB 3.0 eXtensible Host Controller -0100 (Microsoft)”
Is there a new Microsoft driver coming out soon? How about an Intel driver for Windows 8 like the one they have for 7?
Am I the only one who is being slammed with this problem from every windows 8 machine I touch? I have not seen a large amount of discussion on the internet with such a seemingly big thing like USB 3.0 not working with Windows 8!
