I'm trying to get started with hardware monitoring using an AX206 display.

I get an error "cannot find DLL Libusb0.dll

Where am I supposed to find this?

In order to have a proper driver installed for an AX206 device, what you need to do is the following:

1) Download the Samsung SPF LCD driver digitally signed by us (FinalWire) from:


2) Extract the ZIP package into a folder on your PC, e.g. C:\1

3) Right-click on the Windows button on the Taskbar --> Device Manager

4) In the Device Manager look for the device entry for the AX206. It should be inside the group called Other devices

5) Right-click on the AX206 device --> Update driver --> Browse my computer for drivers

6) Click on the bottom button: Let me pick from a list of available drivers on my computer

7) Select Show All Devices --> click on the bottom Next button --> click on the Have Disk button

8) Navigate to the folder where you've extracted the ZIP package into and select the .INF file there

9) In the Select the device driver you want to install for this hardware window feel free to choose any of the devices, e.g. the first one called Samsung 1000P Digital Photo Frame

10) Click on the Yes button in the Update Driver Warning message box

11) You're done with driver installation and can start using the AIDA64 AX206 module ;)

Please note that this process of driver installation applies to both Windows 10 and Windows 11.

Hi, I'm having a problem with the installation process, I followed the above steps but everytime I chose the samsung_spf.inf... it says "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.

Please help.

That's the DLL for libusb. LibUSB is a low level USB driver which allows userspace applications to directly connect to USB attached hardware. Normally, this is installed automatically by Windows when you plug in the target USB device, as there's a set of relevant fields in the USB descriptor. I'd try attaching the device to libusb using zadig.
