aaronfischer [1] filed a deletion request for bcusdk [2]: This package is abandoned for years. eibd does not support ETS5 or other standards, so it is basically useless. A popular fork (knxd, AUR package: knxd-git) are in active development for years. This package just confuses newcomers which are searching for a tool to access the KNX bus. It is safe to delete this package. [1] https://aur.archlinux.org/account/aaronfischer/ [2] https://aur.archlinux.org/pkgbase/bcusdk/
