    Hi,

    I’m sorry for the delay. Thank you for providing all the information about the issue.

    It looks like the nxusb.ko loads correctly after manual compilation. I’d like to ask you some additional questions:

    – Do you see a green dot in the corner of your smart card reader icon in “Menu -> Devices -> Connect a USB Device” tab when forwarding?

    – Do you see both local and remote devices in the tab?

    If you don’t see the devices, especially for the remote side, please make sure that the nxusb module is launched after opening “Menu -> Devices -> Connect a USB Device”:

    – on Ubuntu you need to run ‘ps ax | grep nxusbd | grep -v grep’, the output should be non-empty

    – on Windows you need to go to ‘Program Files/NoMachine/bin’ or ‘Program Files (x86)/NoMachine/bin’ and run ‘./nxservice64.exe –status nxusb’ (nxservice32.exe for 32-bit OS), the output should be ‘Running’

    If you encounter any errors, you can post or attach the output of the commands and/or a screenshot of USB tab.

    Hi,

    >>– Do you see a green dot in the corner of your smart card reader icon in “Menu -> Devices -> Connect a USB Device” tab when >>forwarding?

    >>– Do you see both local and remote devices in the tab?

    Yes, all good, please, find attach.

    Also in terminal:

    $ sudo ps ax | grep nxusbd | grep -v grep

    3745 ?        S<sl   0:00 /usr/NX/bin/nxusbd

     

    Did an additional test.

    On PC installed Ubuntu Server. Connected USB to this PC. USB is working.

    Then installed NoMachine Enterprise Terminal Server Evalution: 7.10.1. And did https://kb.nomachine.com/AR12J00658

    Connected from remote PC NoMachine Enterprise Client.

    The situation is the same, I cannot work with the keys in the session.

    Hello, did you try connecting your smartcard via a dedicated service?

    Here’s how to do it: https://kb.nomachine.com/DT10O00156#4.5
