USB Device Driver Question RRS feed

  • Question

  • I am writing a device driver to support 4 identical USB devices connected to the Host via Hub. All the four have the same VID/PID. The registry entry is HKLM\LoadClients\"VID_PID"\Default\Default\My_USB.  Assume the Dll file is "My_USB.DLL".

    This will be a stream driver. I have the usual exports for Open, Close, USBAttach, etc through the .def file. Assume that I will have 4 prefixes, "USB", "USB2" etc.

    Is there a way to associate, say "USB1" to one particular device?

    Thanks for any assistance
