Can’t uninstall nxUSB driver

[Corscaria]

Ever since installing NoMachine I’ve had a problem with my laptop locking up randomly. Whether or not NoMachine was running at the time. No BSOD, No crashdumps to help me debug the issue, just total system lockup. Cold booting is the only thing that ends the lockup.  I eventually found the following KB entry https://nomachine.com/AR10K00732 and tried that even though I wasn’t getting BSODs. It Worked, sort of…. uninstalling the driver ended the lockups. But, the driver is not getting removed permanently. Every time I reboot the system it comes back, and I have to uninstall it again.

And yes, I followed the KB exactly.

And yes, I install every update, the latest one being installed today approximately half an hour before the system locked up again, even though I hadn’t run NoMachine.

I have no problems with the remote computer.

What can I do to manually remove the driver after uninstalling it, so that it never shows back up again?

 

P.S. I mostly use NoMachine to kill crashed games and install mods. I play the games remotely using Steam In-Home Streaming, which has much better video clarity, and audio, but is very limited in every other possible way. My remote PC is a heavy duty custom built gaming rig, and the laptop is a Sony VCPEB11FX (1st Gen Core-i3 with integrated video, 4GB ram) a neighbor gave me for helping him move.

Hello Corscaria,

Can you please tell us what Windows version you use, as well as the NoMachine version.

And do you use Eltima USB Gateway or any another software for USB devices forwarding ?

Thank you in advance.

Windows 10, Version 1703, build 15063.540

NoMachine 5.3.10.0

No USB Gateway or USB forwarding software.

Did you try something like this:

1. Uninstall NoMachine

2. Reboot the machine

3. Check if “NoMachine USB Host Adapter” appears in device manager. If so, uninstall it.

4. Unregister “NoMachine USB Hub Filter”. To do that, you need to:
a) Open Windows registry: Menu start -> run -> regedit
b) Find the following registry key in the tree on the left:
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36fc9e60-c465-11cf-8056-444553540000}”
c) Find UPPERFILTERS variable on the right side.
Note: it should contain list of registered filters, but maybe it’s empty if no filter is registered.
Edit UPPERFILTERS variable and remove entries containing nx prefix (e.g. “nxusbf”) if they exist.

5. Reboot the machine

Regards.
