The repository contains chrome app that uses chrome.usb API and the source code for the firmware for digispark, that was using to test the issue (the project was started for something like workshop on MCUs).
If you wish, I may provide compiled version of firmware for digispark, if you have hardware for it handy ;). But the issue was reproducible also on other devices, so I believe this is not a requirement.
