ProffieOS Workbench Help


I am running OS 6.6.

Connected to the board (can verify this with the USB icon on the Chrome browser tab)

When I click "USB"on the page, nothing happens. I’m not sure what to do next. What am I missing? TIA!!

You don’t need ENABLE_SERIAL.
If you bring up the javascript console (dot-dot-dot → more tools → developer tools → console) does it say anything interesting or helpful?

This error appears every time I click “USB”.

app.html:1346 Uncaught (in promise) DOMException: Unable to claim interface.

That probably means that some other driver has claimed the WebUSB interface.
You can use this video as a guide for how to check the driver, but please note that this video is demonstrating how to check the driver of the serial port, not the webusb interface:

There was some CDC driver or something in with the proffieboard. Deleted it and we are in action.
