FWIW I get an error 404 there.

A notifier for the usbauth firewall against BadUSB attacks. The user
could manually allow or deny USB devices.
I'm curious: what are the pros/cons compared to usbguard, that's
already in Debian?

Sorry, it seems that github have changed some linking of project subfolders.

The usbguard development was supported by RedHat and usbauth was supported by SUSE. Historical, usbguard was published while the working on usbauth has already been started.

usbauth could allow/deny usb interfaces using the new usb interface authorization mechanism that is part of linux 4.4 and above. See also: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/log/?h=v4.4.94&qt=grep&q=interface+auth

* allow a storage functionality of a USB device and deny USB Ethernet of the same device * allow audio/video functionality of an USB TV card and deny using the remote control functionality * allow USB printing/scanning and deny USB storage usage of a multifunction printer (BTW: the interface mechanism supports denying user space triggered actions (using USB claiming) like scanning)

usbguard could allow/deny USB devices using the usb device authorization mechanism of the Linux kernel. It allows to denying a whole device if one interface of it is considered as bad (usbauth supports this, too)
usbguard allows creating actions that is not supported by usbauth.

I hope this helps. If you can understand German language you could read a detailed description: https://epub.uni-bayreuth.de/3048/1/koch2017sicherheitsaspekte.pdf
