I know there are multiple fixes out there for getting Windows 8.1 to detect HTC phones while in fastboot mode, but some are dependent on whether you have an Intel or AMD processor and USB 2.0 or 3.0. This is the latest fix, and should work on all types of PCs and HTC phones. It worked for me on my computer with Windows 8.1 x64, Intel processor, and USB 2.0.

The issue has something to do with the BOS descriptor in Windows 8.1. It has been fixed in update rollup 2967917.
1. Install update rollup 2967917 for Windows 8.1.
- To check if you have the update installed already, go to Control Panel > Programs and Features > View Installed Updates > type "KB2967917" in the search box.2. Download the attached file Fastboot.reg.txt and change the extension to Fastboot.reg.
- If you don't have the update installed, open Windows Update to install it.
Thanks - the reg patch was all I needed!!
On Windows 10, I was running into the same issue - the Android device (an HTC One S) was available to adb in recovery but couldn't be seen by fastboot when in the bootloader (hboot 2.15). In the Windows 10 Device Manager, the device was showing the "USB BOS Descriptor Failed" & "Device Failed Enumeration - Error Code 43" errors, even though the Android and USB hub drivers were installed.
I tried everything to get the device to be recognised by fastboot but, in the end, the registry patch (at the bottom of the first post in this thread) to skip querying the BOS Descriptor fixed it instantly.
Without the patch, it seems that Windows 10, like Windows 8 before it, is unable to use the installed drivers.
There are lots of other threads where people are having the same problem (Google "technet windows-10-android-fastboot-device-failed-enumeration-error-code-43" for an example from the Microsoft website) but all tend to suggest variations on reinstalling drivers.
