Hello!

I have several Linux clients; all clients are equipped with smart-card readers for authentication issues. Usually as soon as someone inputs a smart-card, a specific script is running and the user gets a windows login (Terminal Server)...

The problem is that on some of the clients, it happens, that sometimes the reader doesn't react.

On those clients, all processes are running, and even with a reboot that smart-card reader wouldn't work. Only with a Power-Off and power-on, the smart-card reader starts to work again.

(It is using the pcsc drivers for linux and the reader is scr331)

Did anybody experience a similar problem?
Or is it possible to reinitialise the smart-card reader without having to power-down the complete system?



Many Thanks and regards


Some additional Info: (Output of opensc tool)
Reader: SCR331 USB Smart Card Reader 00 (Built-in)
Reader drivers: pcsc/ctapi

since no one has replied I would like to offer some suggestions.

1) try swapping the reader from faulty computer to working one...if fault transfers, you may have failing hardware?

2) I gather the 'faulty' readers can be clearly identified....which means you could identify the login user.....I am suggesting you look at the actions of the users who have no faults and compare them to the faulty ones (the reader not the human).....I am suggesting maybe they are doing something like pulling out the card before system is fully booted or some other thing that is tricking the machine to cycle because it was not cleanly exitted?
