Fastboot USB not working, any fix? topic

Hello everyone,

I have seem similar threads about this happening to windows 8 users, but my case is slightly different. as of yesterday my fastboot was working perfectly fine, until I tried to flash this RUU ( I was trying to downgrade my OS so I could use rumrunner to unlock my device), when I tried to flash the RUU I heard the alert message from windows that my phone was disconnected. ever since my pc never recognizes my phone while in bootloader, although it works perfectly fine while on the system.

In the devices manager MyHTC drivers show with the yellow triangle and the errorcode 10 (failed to start devices)
going to leave the links for the screenshots

this is the information displayed on my bootloader

RELOCKED
M7_WLV PVT SHIP S-OFF RH
CID-VZW__001
HBOOT-1.54.0000
RADIO-1.13.41.0421
OpenDSP-V32.120.274.0909
OS-4.10.605.3 (1.10.605.10) This part is displayed in red in the boot loader.
eMMC-boot 248MB

here is what I have tried already.
Install the usb 3.0 windows update( said already had it, plus this was working before so doubt it is the problem)
flash RUU.exe from here
Install and reinstall HTC drivers (multiple times)
restart computer
try different usb ports/cables

and I think this is all I have tried, will keep trying more stuff and update the post with information, has anybody encountered a similar problem or knows a fix?

Thanks in advance
