Connecting and starting to transfer and then disconnecting. Connecting but running at USB 2.0 or lower speeds. I have been using 12 Seagate Backup Plus drives of various sizes with USB 3.0 interfaces for external storage. Xhci controller and uses a via VL810 hub for distribution. This motherboard uses an Intel Z77 chipset. I built a new machine with a gigabyte UD5H motherboard. I have been fighting this issue with USB 3.0 for almost a year. Is there a new Microsoft driver coming out soon? How about an Intel driver for Windows 8 like the one they have for 7?Īm 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! 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? (Before they had limited or no function depending on the controller) Non-Intel USB 3.0 controllers are fully functional at full USB 3.0 speeds. (Before they were also slow but much less functional, often not recognizing devices) The Intel USB 3.0 controllers on the machines seam to only run at 2.0 speeds. "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. My solution: “Intel xHCI Mode” or “XHCI Pre-Boot Mode” in BIOS/Firmware
USB 3.0 Flash drives running slow and/or disconnecting often with data corruption/loss.
