On firmware install: Spike Prime hub did not show DFU device and Robot Inventor did #1690
Comments
Doing the DFU driver steps seems to be required on Windows for every new hub you use. I wonder if Windows "forgets" about certain devices eventually, so it would treat it like a new hub? (Just as it does with Bluetooth devices) |
"eventually" is the key word I think. The last hub I installed yesterday was the prime hub, so to test I now updated the RobotInventor Hub. |
Robot Inventor and SPIKE Prime and SPIKE Essential all have different USB product IDs, so I would expect that we would have to configure the WinUSB driver for each type of hub individually. Windows should not "forget" unless you manually uninstall the driver/remove the device from the Device Manager. |
I think it is each hub, not just each hub type. |
Interesting, I wonder if Windows is looking at the serial number as well when we manually configure a driver. |
Oh, nice - if that means that there might be a slightly different setup path that would make it necessary just once, that would be pretty neat for classroom use. |
For for that, I think https://github.com/pbatard/libwdi/wiki/Zadig can help. It will basically create a signed driver for you that just uses the VID/PID match. |
I suppose we could test if that generic windows driver installer Zadig we had once upon a time makes it necessary once or for every hub. EDIT: beat me to it :) |
I wonder if we could use Zadig to create a |

Thank you for trying this Attila. To be complete, is Zadig required only once per computer, or also once per hub like the device manager method? |
After some time, I wanted to flash newer firmware (for #1678) on the primehub that was still at this CI firmware (build 3380 I think).
Without any change on the windows side tried the same action on a Robot Inventor hub.
And that went fine.
Re-tried the PrimeHub and again no DFU device.
Did a re-install of the dfu driver as you document.
Now the PrimeHub is shown as DFU device and can have it's firmware updated.
So no problem in the end, but I add this in case anyone has this problem too.
