Yes, a circle is rotating. I waited until a red ! is marked on the USB icon. Then I ran lsmod | grep nxusb, but there is nothing returned.

The command lsmod | grep nxusb returns nothing.

I’m not admin so I don’t have root access. I contacted the admin. He said that he did not do anything special to the installation or configuration of NoMachine. Now what? Can you conduct an investigation of the software on your side?

[zhou_heng]

1. How to check whether USB forwarding kernel object is compiled or not?

2. How to check whether the remote Linux is running in Secure Boot mode?

3. How to check whether the admin has disabled USB forwarding/connecting?

I have read the link you gave, but cannot answer the above questions by myself.

The log file is in the attachment: log.zip, log.z01-z03

The screenshot is attached at the bottom. The device titled “Microsoft Corp.” is the game controller I wanna connect.

I tried other USB devices: my Android phone and the USB keyboard, but none of them can connect.

There is no way to restart remote Ubuntu, because it is a node of my institute’s cluster.

Please let me know whether you can receive these files and need more.

Hi, Giorgi-G.:

It does not work. There is a red ! below the icon of the game controller. Ubuntu does not respond to my game controller. But it works if I use the controller locally on the remote Ubuntu, indicating that the driver is installed properly.

Now what?

I asked this question because an older version of X-win32 crashes often on my machine, so I was thinking installing something else as a replacement. Without any answer to the question , I contacted X-win32 developer and got a reply immediately (in 6 hours, immediately compared to yours). Now I’ve installed a new version of X-win32 and it works very well. No need to install NoMachine any more.
