Source: hidapi-cffi Version: 0.2.1-1.1 Severity: wishlist Version 0.2.2 of this software was released (still to GitHub) on 2017-11-22. The changes are: 1. Fix length parameter in send_feature_report 2. Make serial number optional in Device.open.
I've just started experimenting with this package and almost immediately ran into the second issue above, which is a deviation from the documentation. Besides packaging the new version, I'd also suggest adding a debian/watch file based on the usual template for projects hosted on GitHub.
