Hello :
I made a virtul bus driver to enumerate virtul port driver. But I meet a bug, please help me.
When I first install the virtul bus driver, the port enumerated is COM3.But when I unload the drivers and reinstall the virtual bus driver, the port enumerated becomes COM4. And then becomes COM5,COM6,COM7 etc. after unloading and reinstalling. Now I want to know how the system determine which port is the enumerated port or how I can kill the bug.
Thank you very much!!!
