Is there a way to get a reference to an unnamed device?
How can you get a pointer / call CreateFile() from user mode on such a
device?

Thanks.

Most unamed devices have a device interface, these you should be able to
reference, but you do need to know the GUID for the class/device.

SPTD.sys for example creates several unnamed devices.
I used the DEVINTERFACE sample from oney's book to enum all interfaces
but i didn't find any device that seems to match SPTD in some way.
Am i doing something wrong ?

Thanks.
