[Question] Device manager instructions on Windows
Question I try to install Pybricks Firmware on Mindstorms Inventor Hub. Error Msg: code.pybricks.com wants to connect to a serial port - no compatible device found. Can anyone help me?
Context Windows 11, Lego Mindstorms Inventor Hub
Is your Hub in Update mode, as indicated in the video with the red/blue/green lights?
Can you share a screenshot of the error message?
Did you install the appropriate USB driver as described in the instruction? Does the device appear (with the correct driver) in the Windows Device Manager?
I removed the LEGO Technic Large Hub in DFU Mode. reconnected the hub. Windows have no driver Automatisch nach Treibern suchen not driver found the same with windows update tool
it seems I need a Driver! Where to get it? Any ideas?
Please follow the step-by-step installations in the installation dialog. It's all there :)
Yes, it's all there, but where? If you install Pybricks with an unprivileged account (which is reasonable), and you want to update the diver with system privileges (which is necessary), Pybrics will not find the driver. It would be helpful to document the filename and directory. Many thanks!
That is good feedback - thanks!
Which steps looked different in your case and how did you resolve it?
I can't remember what exactly I did. I have now tried different things, but couldn't reproduce the error. I think it's a problem with the directory. As I interpret the instructions, the driver is located in a user directory. There is no directory similar to \Users\pybricks\Documents. Unfortunately, I have no idea where the driver should be and what the file is called. Sorry I can't help any further.
Maybe it's coincidental, but we just got another support email on this topic, saying that there are no "other devices" in device manager.
Maybe we need to review if something changed in Windows device manager so we can update the instructions.
If it isn't there, then it means a driver has already been installed for the DFU device or the hub is not in DFU mode.
It is only there if there is no driver installed already.
Once the driver is installed, it moves to Universal Serial Bus devices.
Or if running official LEGO firmware and not in DFU mode, the hub shows up under Ports.
There is no directory similar to \Users\pybricks\Documents.
The directory does not matter. It is ignored when you click Let me pick.... We could probably delete it or blur it out in the screenshot.
Thank you very much for the answers. The directory was a red herring for me. But now everything works excellently.
