Serenum.vxd support for non Standard Serial Ports ( USB to Serial )

Hi,

We have developed a USB to Serial converter. We have written
the drivers windows-98 SE( WDM driver + Vxd driver ).
This is working fine with the hyperterminal and other serial port applications.

In the registry the Enumerator is specified to be Serenum.vxd

HKR,Enumerator,serenum.vxd

It is my understanding that this VXD is responsible for the enumeration of devices
connected to a serial port and will detect things like PnP modems I have however noticed
that enumeration does not seem to be happening for my serial ports.

When I click the Refresh’ button in the device manager, It is enumerating the devices (Modem)
which are connected to the standard serial port
and it doesn’t enumerating the devices (Modem) which are connected to the Usb Serial port.

Does anyone have any idea why this not work?

Thanks in advance
