Is this Windows 11 or 10? Did they sneak in more security or something?
Before you (re?)-installed the Zadig driver at least it was trying to read.
You didn't install any "official" Qualcomm software, did you?
Edit: Ok, here is a little test program. It's called winusb.prc, just rename it winusb.exe
Code:
C:\>winusb.exe 05c6 9008
Just tell me the results.
