    how can I specify a specific target endpoint for bulkread transfers if my
    device has got more than one bulk-in endpoint and how can I read this
    selection in the DispatchReadWrite function in my driver?

    Thank you

  2. You can read pipe number or symbolic name in Create request.
    This name program can add to device name when calling CreateFile(...)
    This name and device handfle yua can store in jour DeviceExtension structure

    In ReadWrite function you have acces to file handle.

  4. look at the bulkusb sample, it shows how you can do this in the create path
    and then check for it during the read or write path.
