CM_PROB_DRIVER_FAILED_PRIOR_UNLOAD

Hi,

I have a device upper filter driver. First install, uninstall of driver was succesffully.
When I tried again to install another version of driver I receive the following error message: " Device required reboot: Device has problem: 0x26: CM_PROB_DRIVER_FAILED_PRIOR_UNLOAD.".

This error is from setupapi.dev.log file.

How can I fix this error because I need my driver running without any system restart?

Thank you.

You probably have a reference leak on your device object.
