Hi,
 
I am trying to retrieve device-friendly name from class-guid. I am getting an error back indicating INVALID_CLASS_NAME [206] on using SetupDiGetClassDescriptionEx. How-ever, on calling SetupDiGetClassDevsEx with same class-guid to get HDEVINFO it is working fine. Hence I am not sure why I getting the error on only using SetupDiGetClassDescriptionEx. Someone please help.
 
P.S: Any other mechanism of retrieving device friendly name is also fine for me.. Just want a method to get it.
 
Thanks,
Shishir

I think I kind of understand the problem now. The class-guid will not give me the device-friendly-name; I need to have the device-guid.. is that correct ?
 
If so, how do I retrieve the device-guid ? DBT_DEVTYP_DEVICEINTERFACE is giving me the class-interface-guid for all COM ports I think [86E0D1E0-8089-11D0-9CE4-08003E301F73]
