Pybricks Connection Problem #1368

Open sjlct123 opened 8 months ago

sjlct123 commented 8 months ago

I want to connect my Lego Mindstorms 51515 Hub to pybricks and install the pybricks firmware but it dosnt work. I can't even install WinUSB driver. It glitches with error code 10. I was doing it on a lg gram 2022 laptop running windows 11.

I expected the firmware to be installed on my hub correctley.

Does the device show up in the Windows Device Manager as "LEGO Technic Large Hub in DFU Mode"?

Do you have a different computer you could try?

sjlct123 commented 8 months ago

No it doesn't show up as Lego technic large hub in dfu mode it shows up as Other Device and sometimes WinUSB Device. I don't have any other computers to try it on.

Is the Bluetooth light on the hub blinking red (pink)/green/blue/off? If not, then the hub is not in DFU mode and that is the problem. If it is, I would try deleting the device from the Device Manager and start over.

sjlct123 commented 8 months ago

It was in dfu mode but it didn't show up.

dlech commented 8 months ago

Can you share a screenshot of your Device Manager? There should be something in there with a :warning: icon if the driver is not loading correctly.

If you right-click that and select Uninstall device then disconnect the hub and plug it back in (making sure to hold the Bluetooth button to get DFU mode) what does it say?

It dosen't even show up on device manager anymore.

dlech commented 7 months ago

Maybe there is a bad USB cable or something like that?

sjlct123 commented 7 months ago

I tried a different cable but it still didn't work.

On my Windows 11, if I uninstall the device like I mentioned in https://github.com/pybricks/support/issues/1368#issuecomment-1879778338 and then unplug the hub and plug it back in, I see this:

You are not seeing this after following the same steps?

sjlct123 commented 7 months ago

Yes.

dlech commented 7 months ago

I'm afraid I've run out of suggestions. It sounds like there could be a hardware issue on your computer or a broken Windows installation if the device is not longer appearing even after a reboot of everything (the hub and your computer).

sjlct123 commented 7 months ago

I don't think it's my computer. I tried it on another computer but it didn't work. Thank you.
