[Pcsclite-muscle] How to Identify USB devices on linux/ubuntu/debian

[Uv Wildner]

Hello, 

I need to identify the USB device to which a card reader with a specific card is connected. 
I am pulling my hair out but cannot find any API call that provides this information. 

on Ludovic's blog I find this: 
https://ludovicrousseau.blogspot.de/2010/05/what-is-in-pcsc-reader-name.html 

That does not work on my system though! 
ubuntu xenial 4.4.0-59-generic x86_64 

When I list my card readers I get the list of readers like this from SCardListReaders(): 

SCM Microsystems Inc. SCR 3310 00 00 
SCM Microsystems Inc. SCR 3310 01 00 

OK, so the readers are enumerated. 
However, I need to know the usb device id to be able to connect the reader with the right card to the correct virtualization environment. 

Bus 002 Device 008: ID 04e6:5116 SCM Microsystems, Inc. SCR331-LC1 / SCR3310 SmartCard Reader 
Bus 001 Device 005: ID 04e6:5116 SCM Microsystems, Inc. SCR331-LC1 / SCR3310 SmartCard Reader 

I only know that the usb device id can change easily. 

How do I find which USB device has been connected to the the instance of the SCardReader???? 

Any pointers greatly welcome.
