Hi,

NoMachine software supports only USB devices forwarding.

[Giorgi-G.]

Hi,

Can you please share with us Windows and NoMachine’s versions?

Once the Yubikey is forwarded as a USB device, do you see it in the remote machine’s devices manager as a USB device?

Have you tried to forward any other USB device to the same machine and check if it works?

[Giorgi-G.]

Hi,

Can you please post a screenshot of the Devices -> Connect a USB device tab?

Also if there is any chance, please try to forward any other USB device (i.e. flash drive, or mouse), so we can find out if it’s a device-specific issue or not.

[Giorgi-G.]

Hi,

Yes you are right, the folder:

/Library/Application Support/NoMachine/Extensions/

for your OS version should contain at least the following files:

nxusbproxy_11.0.kext<span style=”white-space: pre;”>
</span>nxusbvic_11.0.kext<span style=”white-space: pre;”>
</span>nxusbvhci_11.0.kext

Please try re-installing NoMachine’s latest version.

[Giorgi-G.]

Hi,

Can you please share the NoMachine version you have installed on that VM? If it’s lower than 7.7.4, I would suggest updating.

In addition please take a look at this article: https://knowledgebase.nomachine.com/AR01P00962

Hi,

Can you please run this command in the target machine and print the output here?

ls /Library/Application\ Support/NoMachine/Extensions/

 

[Giorgi-G.]

Hi, have you allowed all NoMachine drivers on the macOS side? Some instructions for that can be found here https://knowledgebase.nomachine.com/AR01P00962.

[Giorgi-G.]

Hi,

There is a way to simply self-sign nxusb.ko driver on your side, the detailed instruction can be found here: https://knowledgebase.nomachine.com/AR05O00929.

[Giorgi-G.]

Hi,

Please run this command in the terminal

ls -l /Library/Application\ Support/NoMachine/Extensions/ | grep nxusb

If the output is empty, the patch we sent you yesterday should fix it.

[Giorgi-G.]

Hi,

That seems you have a similar issue that is described here.  https://forums.nomachine.com/topic/nomachine-for-mac-does-not-install-usb-kext

I will send you a patch that fixes that issue.

Hi,

Please look at this article to:

How to enable USB devices forwarding on macOSX
https://knowledgebase.nomachine.com/AR01P00962

[Giorgi-G.]

Hi,

Can you please connect to macOS VM, go to USB devices forwarding tab, wait until local and remote devices will be loaded and after run the following command in the cmd and send its output.

sudo kextstat | grep nx

[Giorgi-G.]

Could you please clarify, what kind of Hotplug you trying to use?

In general, if a device is listed in NoMachine’s USB devices forwarding tab it should be possible to forward it.

[Giorgi-G.]

Hi,

Could you please check if you have enabled extensions loading on your macOS machine?

https://knowledgebase.nomachine.com/AR01P00962

Also, could you please send logs from Raspbery PI? And check if nxusb.ko is well compiled on it?

https://knowledgebase.nomachine.com/AR11O00946

[Giorgi-G.]

Based on your logs, I don’t see any issues with the USB forwarding module on the Windows machine.

To be 100% sure, could you please

1) send us a screen from Devices Manager

2) send a value of

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36fc9e60-c465-11cf-8056-444553540000}”

registry key. To find it out, open Windows registry: Menu start -> run -> regedit; find the mentioned registry key in the tree on the left; find UPPERFILTERS variable on the right side and send it’s value.

Also if all your VM’s are on the same VM host, I would suggest checking if their USB drivers are enabled and supported by VM by itself. The same type of logs from VM Windows machine could be helpful.
