Solved Can not connect to DWC

[anagh]

Hello everyone,
When I try to connect to the controller through DWC, this is the error message I get: Connection interrupted, attempting to reconnect. Cannot set properties of undefined (setting "spindle").
Any suggestions?

What do you have in your config.g?

How did you update to 3.4?

@phaedrux Quick update: I did the whole setup from scratch using the latest (stable) versions for the firmware and DWC. That seems to have fixed the issue.
