I want to  use mini-dm on windows10,

First I installed Qualcomm USB driver (under Qualcomm\Hexagon_SDK\3.5.2\tools\debug\usb\setup.exe)

But when I run com_finder.py, outputs "No comm port found for Qualcomm HS-USB Device"

I uninstall and reinstall the drivers. the error persists 

(python27) C:\Qualcomm\Hexagon_SDK\3.5.2\scripts>python com_finder.py
 
        No comm port found for Qualcomm HS-USB Device

Same here.

Done install Qualcomm USB driver by QPM.

Running on Windows 10 22H2.

 

FYI.      I checked the python script and found that the main difference is the filter string between "ListPorts" and "FindQualcommUSBPort". So I assume COM6 is reachable if it shows some message like following "List of ports found containing 'Qualcomm HS-USB':         Qualcomm HS-USB QDLoader 9008 (COM6)".  Thus I changed the filter string from "Qualcomm HS-USB (Android DIAG|(MSM )*(Diagnostics))" to "Qualcomm HS-USB", and it does no harm so far.  For one thing to be noticed, I'm using SDK 5.2.x.

It seems Qualcomm has changed some of interfaces and contents since version 4.x.x.
