devcon.exe update failed for installing RNDIS driver

Question

Hi,

I have followed the instruction here to install the windows kits:

Windows Device Console (Devcon.exe) - Windows drivers | Microsoft Learn

Additionally, I have followed the suggestion here by disabling the driver signature enforcement

I am using both of the following commands to update the RNDIS driver:

1. devcon -r update ".\mod-rndis-driver-windows\RNDIS.inf" "USB\VID_20D1&PID_5E26"
2. devcon update ".\mod-rndis-driver-windows\RNDIS.inf" "USB\VID_20D1&PID_5E26"

but I got the following error message:

"Updating drivers for USB\VID_20D1&PID_5E26 from .\mod-rndis-driver-windows\RNDIS.inf.

devcon failed."

From the error message, I cannot figure out why the command failed. Additionally, I am able to update the driver for the same device from device manager with the same RNDIS.inf. Do you probably know why it fails when using the devcon.exe? I am looking forward to your early reply. Thank you in advance.

Best Regards
