UMDF2 Virtual Serial Driver shows exclamation marks (crashed) in Device Manager.

Following are the errors messages/status from Property Page:

Device Status: "Windows has stopped the device because it has reported problem (Code 43)"
Problem status: "Request is not supported C00000BB".

Windows events log or driver logs do not has any details on the errors. Issue could not be reproduced.

Any idea on what are possible ways to figure-out the issue?
