15’s release notes say something about production quality, also for USB, so lets hope they mean it.
For the HID part, I totally forgot about the STM specific implementation. Still, the 52840’s integrated USB is a pretty cool thing and makes that dongle so interesting.
I had a look at the HID examples yesterday but had troubles with flashing existing example hex’ and getting some if the tools to work. Seems I have to recompile using the full tool chain.
The dongle is brand new and the desktop integration might still need minor work/updating.
I‘ll post an update if I got something going Espruino-wise.
