USB Function - No events received after Reset event

[Keshava GN]

Hi all,

I'm developing an app based on GenericUSBFn Class driver. App uses IOCTLs as per this documentation: Communicating with GenericUSBFn.sys from a user-mode service - Windows drivers . On device side I get following events:

UfnEventAttach, UfnEventSuspend, UfnEventReset

I'm not receiving any other event after these 3 events. Can someone help me why this could be happening?


Thanks.

With regards,
