Re: [9front] [PATCH] Fix nusb/audio /dev entries

["Sigrid Solveig Haflínudóttir" <sigrid@ftrv.se>]

Write a tool (script?) that watches usbevent and does that. Run it in the right place so that namespace is updated properly for your programs.
Bonus: a tool (I'd suggest separate from mixfs) that does that but also provides its own /dev/audio that never craps out on writes unless there is no audio devices at all, and can be configured in runtime to point at different "real" devices for input and output.
That might be more useful than nusbrc running nusb/audio and modifying the namespace when one least expects it.
