Hi,

can you give me some advice:
which card readers for pcsc-lite have serial numbers?
with "lsusb -v" I find this:
Bus 004 Device 012: ID 04e6:5115 SCM Microsystems, Inc. SCR335 SmartCard
Reader

...
  idVendor 0x04e6 SCM Microsystems, Inc.
  idProduct 0x5115 SCR335 SmartCard Reader
  bcdDevice 5.14
  iManufacturer 1 SCM Microsystems Inc.
  iProduct 2 SCR33x USB Smart Card Reader
  iSerial 5 21120443106689

hurray, a reader with a serial number. I'm told by some people that
many vendors have no serial number in their readers or only a dummy
value.

So can anyone suggest even more reader with serial numbers?
Of course I had a look at Ludovics ccid driver with the
reader/ directory, but all those txt files do not include
"iSerial" field.

bonus if you have the same reader twice and can check if the serial
number is different. :)

And the second part of my question is: can you use pcsc API with
pcsc-lite and some driver (ccid prefered of course) to query all
readers including the serial number, so you don't have to rely
on usb plug-in order?

maybe there is even a portable way that works on windows too?

Thanks for your help!

Best regards, Andreas
