How to find the device instance id of a PCSC reader

Question

Having only a handle and context to a PCSC reader using winscard on Windows >= XP, is there some way to get its device instance id or something else that can be

Answer 1

From my tests, it seams that scard service assigns the name in this order:
a) SPDRP_FRIENDLYNAME if present
b) SPDRP_DEVICEDESC

This way, I was able to match the SCardListReaders() names with the rigth Device/Driver.

Hope this helps ...
