I did a clean install of Windows 8.1 with our 8.1 Enterprise ISO. I installed all the drivers available from Acer's support site. However I noticed that I have an Unknown USB Device listed under Universal Serial Bus controllers in Device Manager. The device Hardware ID from properties shows USB\DEVICE_DESCRIPTOR_FAILURE.
Anyone else have this issue from a clean install of Windows 8.1?
Device Manager listing of USB Controllers on my S7-392-9890 upgraded from Win8 Home to Win8.1 Pro
Universal Serial Bus controllers Generic USB Hub Intel(R) 8 Series USB Enhanced Host Controller #1 - 9C26 Intel(R) USB 3.0 eXtensible Host Controller - 0100 (Microsoft) USB Composite Device USB Root Hub USB Root Hub (xHCI)
Noticed in Device manager, used "View" "devices by connections", if a USB 2.0 hub/device was connected to "USB enhanced host controllers" (ie. USB 2.0) would make the "unknown usb device" to work properly.
But in most cases, USB 2.0 devices/hubs would connect under "USB 3.0 extensible host controller" , even if a USB 2.0 device/hub was in fact being connected to a USB 2.0 host controller/hub.
Hi Andyliang Thanks for trying to help. But computer said not compatableb with that software. I decided to return the USB hub for another brand, a name brand this time hoping that will work. Belkin will have teck support.
