[Q] Unrecognized Device only in hboot/fastboot

Let me say beforehand that I am a lifetime lurker. I would not be posting here if I hadn't already spent at least two days scouring the web for an answer.

My HTC Desire HD cannot connect to HTC Sync, but it can connect as a storage device, and can be seen by adb. Whenever it connects while in hboot/fastboot, it will flicker "USB" a few times before Windows tell me it's not recognized (Device failed enumeration code 43). This includes using the RUU wizard from HTC. That will just make it stick on "RUU" in the bootloader.

I have tried every driver download suggested on this site. I have switched USB cables three times (all htc cables). I have used two seperate computers (Windows 8 and Windows 8.1).

I'll admit I'm a nooby specifically to Androids. All I want to do is flash new ROMs/root my device. As far as I know this is step one, and I can't go any further until I've unlocked my bootloader.

EDIT: SOLVED
HTC Desire HD drivers really hates Windows 8 and 8.1. Installed Windows 7 32-bit and it worked just fine.

That error can be a pain in the ass. I have it as well. I believe disabling griver signature enforcement in win8 (it's your OS, isn't it?) should allow installing adb drivers, but I was too lazy to check it. As a workaround I instead flash the boot.img in bootloader by putting it to PD98IMG.zip

I can upload you a template, leave the txt in it and replace the boot.img with your desired one, choose store (none) compression level, then put the zip directly (don't use folders) in sd card

EDIT: I didn't fully read your post before. If you don't have S-OFF most probably you can't get away without adb drivers..

I have those drivers. I installed them manually. I tried the updating the drivers through device manager and pointing them directly to the drivers folder I need, and Windows is insistent that not having ANY drivers installed is the best driver to have installed for my device. :(

I am getting a pop up saying that the device is failing to to start. It's not like other usb devices I might have plugged in and they just sit there in at least their correct category in device manager.

The part that ticks me off most, is that this exact problem on this exact model has been solved on three different forums, and each time the OP just said "nvm I fixed it" and never even bothered to explain how for the rest of us.

It's really hard not to curse right now.

Ya, I had tried that too. None of them will work. It says the file I chose doesn't have compatible software for my device.

Once again, this only happens in the hboot/fastboot/RUU. Once the phone has loaded the OS it works totally completely fine, save for HTC Sync not seeing the phone and vice versa. I don't understand why some drivers would only work sometimes unless something is wrong with my bootloader, and if so, how do i fix it?

Nothing is wrong with your phone, same thing happens to me, I just thought disabling driver signing should fix it, like I said I was too lazy to check it since I found workaround for my needs.

Power down DHD and connect it to PC. I realized, my win7 was installing drivers, while phone was off.
It appears to be the same device/drivers when powered off or when in the Android environment. While in the bootloader, it shows as an unknown device.

I also noticed that only when I am trying to update via RUU, it says instead "Device Descriptor Request Failed"

My drivers list does not show the Google or HTC drivers like yours does after installing all the things in your links. In fact, that's the fourth time I've downloaded those Google/HTC Win7 64x drivers from people around the web. They are not in my drivers list after installing them via the INF files. I must be doing something wrong.

Did you browse to the folder where the manual driver files reside?

To be exact I have:
  • Tried HTC Sync
  • Tried HTC Drivers Installer
  • Tried to Automatically search for drivers
  • Tried to install drivers by using the inf Install option
  • Tried to manually select drivers by pointing to the folder the Win7 64x drivers were placed
  • Tried to manually install by picking out the exact inf files
  • Tried to install from device drivers list, were they were not listed
  • Tried these steps with driver signing turned off
  • Tried all of these steps with another PC

I still think the issue is related to the fact that it only has problems in the bootloader menu

Ok, like u know I had this issue. Now I randomly managed to fix it when I needed adb drivers for my new toy (Sanei tablet for 40$ lol)
The mistake I was making is that I was trying to install the drivers while device was in fastboot, but apparently you can get away with casual "My HTC" drivers which can be installed when DHD is booted into Android. It looks likethe phone is not being detected from bootloader (it doesn't like any of the drivers I had tried), but I can fully use ADB while it's in recovery or starting/trying to boot OS, so it should be enough for rooting/unlocking bootloader.

I remember with HTC Wildfire I had drivers package with seperate drivers for Android and fastboot, so I had to install different driver after rebooting to fastboot, but with these new drivers and win8 it doesn't work out this way.
