A few USB devices when connected to a port of an Enhanced Host Controller (EHCI) might not enumerate on Windows 8.1 but work on Windows 8. In Windows 8.1, the failure is reported as error code 43 in Device Manager. One of the reasons is that the device reports itself as supporting a USB version greater than 2.00, but does not provide the required BOS descriptor. As per the official USB specification, a USB device with version greater than 2.00 must provide a BOS descriptor.
In Windows 8, the USB 2.0 driver stack does not validate that requirement. As a result, a device with version greater than 2.00 and without a BOS descriptor, enumerates successfully when connected to an EHCI controller.
In Windows 8.1, the driver stack has been updated and enumeration fails for such devices.

This method is tested and working with Intel’s USB3.0 controller under Windows 8.1 x64. 1. Download Intel(R)_USB_3.0_eXtensible_Host_Controller_Driver_MOD.zip and extract it. 2. Reboot windows with driver signature disabled: configure->change pc settings-> update & recovery -> recovery-> advanced startup -> troubleshoot -> advanced options -> restart -> 7 3. Open Windows Device Manager, Go to Universal Serial […]
Comments on one of them does mention success but I remember trying both methods and not succeeding. I thought there was a third blog post as well where there were many comments saying that it doesn't work.
I got the driver to install on 8.1 by using the Rockchip Driver Assistant 4.1 driver and running the following registry additions to overcome the BOS Descriptor problem .....
