Ralph,
I'm starting to get my head round this and think that I have a fighting chance
of sorting it out. However, I have a couple of queries (so far), both coming
from the C++ code in your second link.
1. In the first major comment block, the author says that he made the
following: File: /etc/udev/rules.d/39-usb-alsa.rules.
Why 39-usb-... and not just usb-... ?
2. Is there any reason why the author used C++ rather than C for this
application? Just personal preference or is there some benefit in this case?
