I found:

In order to use libusb on Windows you need to install the WinUSB.sys

So please use zadig and change the driver for your device to WinUSB

Yes, I have tried without the driver first, which I uninstalled via USBdeview. The robotarm program ran and reported nothing when I did that.

And, yes, I had to use the zadig program to change the driver for the Robot Arm, to WinUSB.

You can simplify the code, when you use

*handle = libusb_open_device_with_vid_pid(#Null, $1267, $0)

is_interesting() can be removed and also the complete device_list() stuff.
