ADVANCED:USB composite device driver porting

NTDEV
1

Hoi,
The driver runs on Windows 2000. It makes the installed USB device behave as a
USB composite device(multiple-interface USB devices, for this driver, it
created one USB Modem, and two USB Diagnostic Serial Ports). since the driver
is NTDDK-based, surelly it is developed in WDM.

Now, I want to port this driver to Windows 98 SE. But I have several questions
on it.

1.Do I have to create several drivers for each interface of the USB device?
That is, one driver for creating a USB Modem, and one (or two) driver(s) for
creating USB Diagnostic Serial Port(s)?

2.Do I have to implement the driver for USB Diagnostic Serial Ports in VxD?
or I may only modify the existing WDM one?

3.Since so many structures, macros and functions(call) in NTDDK are not
supported by 98DDK, how can I make it work on Windows 98 SE? Walter Oney’s
WDMSTUB or any other better ways?

solution to these questions means a lot to me, hope you can lend me a hand.

Best Regards.

If the modem interface is CDC compliant, should be able to use usbser.sys. usbser only supports a subset of the serial port interface. If that subset meets the requirements for your diagnostic ports (and they also conform to the CDC spec), you might be able to use it for the diag ports as well.
