That's too bad. :( A smart card reader is not always a USB device. When PC/SC was designed smart card readers were serial devices connected to a serial port. > I wonder where that information about the device to card reader mapping gets lost, as it obviously is needed somewhere in the stack?!?! The information is present in pcsc-lite and in the CCID driver. For example pcscd calls libccid with a parameter like "usb:08e6/3437:libudev:0:/dev/bus/usb/001/002" http://pcsclite.alioth.debian.org/api/group__IFDHandler.html#gabb9fe35a68fa080ce9397f0b830b1e7e My question was and still is: why do you need this information at the application level?
