Hi I installed on your Raspberry Pi your latest version of NoMachine.
From Raspberry Pi 3 I connect to virtual machine Linux (I’m testing zorin, ubuntu, centos).
NoMachine recognizes the smart card reader (omnikey 3021) connected to the Raspberry and says it will be redirected to the virtual machine, but on the virtual machines the program I use for the digital signature says that there is no card inserted in the reader.
The smart card chip is oberthur.
The software used for digital signing is Dike and Arubasign.
We checked forwarding HID Omnikey 3121 on Ubuntu 16.04 and it works correctly. However on Ubuntu 14.04 the card wasn’t visible. But it also wasn’t after plugging in the smartcard to the machine. So it looks that system doesn’t support this device.
