I'm struggling with a Smart Card reader in a guest session under Linux Mint 18.2.
Operating public computers, I've set up a customized guest session (thanks to Sonya, lightdm is now the default greeter which made new setup easier), the guest user is loaded from a template one (inspired by https://sites.google.com/site/easylinuxtipsproject/2 and https://help.ubuntu.com/community/CustomizeGuestSession).
I need my customers to be able to use their ID cards trough a Smart Card Reader but it seems that the guest user can't access the device although it's listed by lsusb in a guest session terminal :
Code: Select all
guest-azeyoi@virt0001 ~ $ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 072f:9000 Advanced Card Systems, Ltd ACR38 AC1038-based Smart Card Reader
Bus 001 Device 002: ID 80ee:0021 VirtualBox USB Tablet
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Note that regular users can fully use the device (even the template user upon which is based the guest-session). Note also that i have the same issue both on a virtual machine and a physical one.
Is USB access restricted for the guest user ? I have no troubles with USB storage.
Thanks for the reading,
