NOTICE aboud usbguard and usbauth:
The usbguard project provides an USB firewall, too. It is already packaged within debian.
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.
The main difference is that usbguard works with USB devices and usbauth works with USB interfaces.

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

Examples:
* 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.
