using a local device for remote winlogin

I have a custom gina that replaces msgina.  It supports a usb fingerprint reader to log in to the windows machine.  How can I redirect this login to look for the reader on my local machine when connecting to that pc through remote desktop?

IMO that could only work if the same GINA is used on the remote machine and you provide a way to remotely access that reader via a proxy app or service that send the data to the remote GINA. I am not aware that Windows comes with any stadard or prefabricated ways to do that.

That's what I'm looking for guidance on, how to provide a way to access the local usb device.

Doesn't it come with a driver to read the data? There should be some documented IOCTL code to send to that driver using 'DeviceIoControl()' (http://windowssdk.msdn.microsoft.com/library/en-us/devio/base/deviceiocontrol.asp). See http://msdn.microsoft.com/library/en-us/devio/base/calling_deviceiocontrol.asp ("Calling DeviceIoControl") for a sample. Sorry for being so 'general' about this, but I can't see how I could be more specific at the moment.

BTW, if you are lucky, the device might come with an SDK that 'wraps' this functionality. But, without even knowing what device tht actually is, I can't tell...
