Hello.  I was determined to get this solved myself, and I have spent a lot of time going through the docs and forums.  But I’m stumped.  I’m sure it’s been solved before, and even a pointer to the solution would be great!
My situation:
Server: Ubuntu Mate 20.04, Nomachine 7.6.2 linux
Client: Ubuntu Mate 20.04 Nomachine 7.6.2 linux
I can open the client session with no problems.  But when I go to the menu and tell it I want to import a USB device, the Local section is empty.  I should add that I have plugged the device ( A Logitech Remote Controller ) in to the client, and it is listed in the “lsusb” output.
But on the server side … nothing!
I’ve done a few checks after reading previous posts.  /usr/NX/bin/drivers/nxusb.ko does exist on both machines.  lsmod does not show the module in use when the nx software is running.  I can’t see any clues in any of the logs … I do a “grep -i nxusb *.log”, and I get a couple of errors from nxerror.log ( Unknown option: usbport ), and some normal looking commands from nxupdate.log and nxinstall.log.
I’d really like to know what I’m missing here.  I’m happy to do the work, but I don’t know what work I should be doing!
TIA
