Windows 10: ECHO sample kernel mode driver install failure with devcon.exe

I am trying ECHO sample kernel mode driver provided my MSFT samples using devcon.exe. When I install sample driver on windows10 it works fine, however when I install same driver on windows 11 I am noticing below error in windows event log “ROOT\ECHO\0000 had a problem starting. Problem Status: 0xC00000E5" Can you please help resolve this issue?

DevCon UpdateDriverForPlugAndPlayDevicesW API logs Error in event viewer even on success.

Hi,

I have recently noticed that if we use devcon.exe (C:\Program Files (x86)\Windows Kits\10\Tools\10.0.22621.0\x64) to install a kernel mode driver then though installation is successful and driver is in running state but still it logs an error event in event viewer with following details.

On debug I've found that as soon as below API gets called we see error entry in event viewer. Even though API returns success.

if(!UpdateDriverForPlugAndPlayDevicesW(NULL, hwid.c_str(), infpath, flags, &reboot)) {

{

}

I have checked devcon install with windows sample driver as well, and seeing same problem.

Note: Issue is not observed in windows 10 OS. it only appears for windows11

Is this a known issue, how can we fix it with devcon.exe install?

Kernel Mode Driver error

Hi all,

I've been using ATITool for a while now, and it was phenominal. However, the other day I ran into a virus, and had to reinstall my OS (Windows XP Pro 32-bit). After I ran automatic updates, installed all the latest drivers, and etc., I now get the error "The Kernel Mode Driver does not seem to be working." I'm running on XP32-bit, as should be fully updated thanks to automatic updates. I don't know what the problem is. Does anyone know what is going on? And for that matter, what is the Kernel Mode Driver?

 

Kernel mode driver problem

It still doesnt work. It gives me the very same error. Anyone know what a Kernel Mode Driver is? Because this seems to be the problem
