Need help with fast boot

I'm trying to relock my HOX to send in for warranty repair, but I'm having problems with getting my computer to recognize my HOX device in fastboot mode. Fastboot devices does not return any devices. I've tried the following suggestions/fixes posted in other threads:
-Verified fast boot mode is enabled in power settings menu
-Verified USB debugging is enabled
-Uninstalled and reinstalled HTC Sync
-Verified HTC Sync was closed, prior to using fastboot
The problem appears to be with the USB drivers not installing properly. I can't get my phone to be recognized by HTC Sync. With fastboot OFF, USB debugging OFF, HTC sync ON, I receive one of the following 3 error messages.
"USB composite device" driver not installed/recognized
"USB Mass Storage Device" driver not installed/recognized
Unknown device
If Fastboot or USB debugging is on, I get unknown device.
I've tried installing drivers through windows device manager, but that doesn't work either.
Any help would be appreciated.

Download the driver installer from HTCdev and run it.

Are you referring to the drivers installed through HTC sync or is there an alternate file of drivers?

?? There is USB debugging in boot loader screen?? You should just need adbwin and fast boot in PC folder. Hold power and volume - down. Then fastboot oem lock.. is that what our trying to do?

No, there isn't an option for USB debugging on the boot loader screen. A thread I saw said to make sure USB debugging is enable, not sure if it matters, but tried it anyway. "Fastboot oem lock" results in waiting for device, which makes sense since my USB drivers aren't recognizing the device.

Therevis no debugging option on the bootloader screen the only one is under settings developer options first option enable usb debugging.
Edit
Have you tried using a different port on your pc?
Have tried a different cord?
Edit 2
Turn off fastboot in setting then boot into bootloader. Once in bootloader make sure fastboot is highlighted then hit the power button it should then be in red if done correctly.

Make sure you download HTC drivers. Link on this thread:

And make sure you are using the OEM micro USB cable and not some third party one.

[Q] Fastboot AC windows Vista drivers?

I've got a rooted but not s=off HTC One XL which I'm trying to do s=off and get back on the latest version of CM. The problem I have is that I can't get fastboot to work anymore. From a command prompt I can do adb devices and get a response back that shows my phone. I issue the adb reboot bootloader and my phone reboots into the bootloader. The problem is it says fastboot ac and fastboot devices shows nothing. There are several odd things which partially leads me to suspect that my phone has something wrong with it. The only device that will show my phone through adb is my wife's ancient laptop, and I get a message about the USB port slowing things down. My work laptop, personal laptop, and PC all refuse to see the phone despite downloading HTC Sync, installing it for the drivers and removing Sync. Only the old laptop gets as far as the adb devices to work.
When I boot into bootloader, Windows Vista gives a message about unknown device and the device manager updates from showing the phone under Android and MyHTC to going under Universal Serial Bus controllers and showing as an unknown device. I try to update the drivers and point at HTC driver and windows lies to me and says that the best driver is already installed.
I'm at a total loss and can't find anything else to try. I have also used two different cables with the same results, one is a generic USB cable and the other is an HTC cable. I can mount the phone as a USB drive and copy/paste files. It is only in the bootloader that the phone becomes unknown.

Try using a linux bootable usb stick or a windows vm. It's more likely that something is interfering with the driver.

[Q] [Help] fix soft brick sensation s-off

So I was given another HTC sensation recently but this time it's bricked and I don't know how to fix it.
I have a working HTC sensation phone to test that the driver work on win 8.1
The problem
When turning on the phone it goes to a black screen with HTC logo in the middle and 4 small triangles with exclamation point in each corner, from here I have to take out the battery to turn off the phone.
Holding Power+volume down brings up this screen as well so I can't get into bootloader/hboot using pwr+volume down, same thing with plugging in phone to usb
What I've been told
phone is s-off (I assume this means it has a some sort of custom recovery)
bricked when pulling out cable during RUU while trying to return to stock
What I've done/know
windows 8.1
plugged to USB 2.0 port
USB device not recognised when plugging in phone, in device manager in Android HTC device properties
This device cannot start. (Code 10)
A request for the USB BOS descriptor failed.

disabled driver signing security
install Android Universal Naked Driver in Win8 test mode
install Minimal ADB and fastboot utility
adb devices doesn't list any device
other adb command give "error: device not found"
fastboot command produces "waiting for device"
same with fastboot getvar cid
Thank you for any assistance you can give

"USB device not recognized" when flashing new recovery

Hi,
I am trying to update the custom recovery on my HTC Desire S. However, my PC does not detect the phone when in hboot or fastboot mode (but it does when in recovery and when OS is loaded).
When I connect the phone to USB in hboot/fastboot mode, it shows "hboot usb plug" or "fastboot usb" for maybe 10 seconds, but then stops shoinw "USB", and windows shows message "USB device not recognized".
Any suggestions what I should do?
The PC is running Windows 10 Pro, the HTC drivers were installed with HTC Sync 3.3.63 and I installed Android SDK today.
I hope someone can help.

HTC one E8 Dual SIM (M8SD) Unlock Bootloader Error

Hi
I was trying to unlock my htc one e8 dual sim bootloader but i cannot get the device to be indentified as adb device. Here's what i did
1) Installed Android SDK platform tools and google usb driver and downloaded the fastboot binaries from htc dev
2)Installed htc sync manager for the drivers
3)Enabled USB debugging on phone
4)When the phone is turned on, it is shown in the adb devices list BUT as soon as i boot it in fastboot, it is not listed. I have tried installing the google usb driver , connecting it in Charging and Media Transfer mode but to no avail.
My laptop has only usb 3.0 ports
Kindly Help Me
Regards

Well... if you have the proper drivers installed, when you turn on the phone with the Vol - and PWR combination, you boot first on HBOOT, you must select Fastboot and then let the drivers get installed, thats the only way
