I started the Installer v2 and confirmed the security alert (accept changes).
The installer proposed to install here:

C:\Program Files (x86)\Inkscape\share\extensions\UBWDriverInstaller

Since I use the 64bit Version of Inkscape 0.91 (as recommened by the online AxiDraw V3 installation instructions), I changed the folder to.

C:\Program Files\Inkscape\share\extensions\UBWDriverInstaller

I did not have to confirm any Admin Rights / Missing Driver Signature dialog and I did not get any other dialog messages.
I looked at the install log (green on black background) and everything worked fine. No error messages.

I then connected AxiDraw to the power outlet and then connected AxiDraw via USB cable.
Again, nothing happened (no “USB device connected sound”, no blinking, no movement, no sound of AxiDraw).

If I started Inkscape, and tied to query the version or raise the pen and stop the motors, I still got the error message

Failed to connect to AxiDraw

The AxiDdraw Control displayed Version v.1.7.8 2018-04-22.

I then opened the directory
C:\Program Files\Inkscape\share\extensions\UBWDriverInstaller
in the Windows explorer and manually started
I had to confirm that I want to perform changes on my machine, which I did.

A window opened where I clicked the “Install Drivers” button.
I did not get any error dialog message and the following information was displayed

Starting driver installation. Please wait …
Complete: Driver was pre-installed to the driver store successfully.
Note: If the Found New Hardware Wizard appears upon plugging in
the device, allow Windows to search automatically for the driver.

I then unplugged the USB cable and re-inserted it.
Nothing happened (no USB device connected sound).
I restarted Inkscape and was still unable to connect.

I unplugged AxiDraw (USB and power).
I restarted the computer.
I connected AxiDraw (first power, then USB).

I am still unable to connect.

There is no light, sound or movement of AxiDraw. The round thing next to the power supply plug gets a little bit warm, but that’s it.

Please advise how to proceed.

I bought the device here: (France).
The serial number of my device is S/N: A3-0078

Best regards,
