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

[Uv Wildner]

Well its easy to specify the device for the docker container.... that's resolved already. 

However, the IDs on the USB bus are not fixed for a physical device and cannot be used reliably for this. 

So I don't know which card is in which physical USB device XXX on the bus. 

But how can I find the mapping from the physical device to a USB device id which I can give to the container to connect the right device. 
This was my original question. How to find this mapping! 

I can list the devices on the usb bus. 

I can list the enumerated readers... and read the contents of the inserted cards. 

How the cards read with an enumerated card reader name are connected to a physical reader AKA ID on the usb bus is hidden in the stack! 
:( 

As in your original answer... it does not seem possible. 
At least not within the pcsclite library. 

cheers

You have a problem with your container software if you can't specify what specific USB device is attached to what specific container. 
The problem is really not at the PC/SC level. 

Good luck
