There is the dali-interface Python library which seems to support a few PC DALI interfaces based on USB-HID and serial. I don’t know how well the translation between USB-HID/serial and DALI is standardized, so I can’t tell you how compatible this library is with DALI interfaces that are not explicitly listed in the README.
Software using this library includes dali_mon for monitoring the DALI bus and dali_cli for sending commands.
