So this is fine now with the latest version?  Note that 015 was released
way back in 2022 and that is even quite old, 017 is the latest release
of usbutils.

A problem in usb-devices was fixed in the 015 release, dealing with
recursion and overwriting existing variables, so odds are that is what
fixed the problem you were having.  Please just use that or newer and
all should be fine.
