I have problems that Windows security is stopping the driver for SSH communication over USB. Suddenly the SSH communication stopped working and I got a failure message on the driver. Are there any new drivers update? [Designer]

Did you perform windows 11 update recently? Are you using this driver currently? https://source.sierrawireless.com/resources/airprime/software/drivers/windows/q/m2m-windows-drivers-qmi-build-5413/

No, this has worked after the update to Windows 11. I have tested this on 3 other computers where it works so it is related to this specific computer.

then this is just particular PC problem You can see if issue is solved by installing the driver. Or you can consider to use linux PC.

I believe this could be due to a new Windows Driver Policy introduced in April 2026. I’ve seen the same error code. Please have a look at the links below. The Windows Driver Policy | Microsoft Support Advancing Windows driver security: Removing trust for the cross-signed driver program

I have also come across this issue and it is indeed to do with the WHCP. Do Sierra Wireless plan on resolving this issue? Right now my customers cannot use my product due to this issue.

Wp76 supports ECM instead of NCM Wp76 also supports RMNET

I need to be able to SSH into the WP76xx from Windows. If I’m not mistake, RMNET doesn’t provide SSH but ECM and NCM do.

the ECM driver is not HLK-ed (Microsoft signed) from the beginning of WP76 program. Customers will have to use test mode if the ECM interface is needed.
