: Hi Warner,
: 
: Applications that use /dev/ugen, needs to be recompiled at least and modified 
: to open /dev/ugenX.Y.A.B instead of /dev/ugenY.B .

Any reason not to provide the old name as an alias to the new?

: I recommend people using the libusb or libusb20 API. Using a library makes 
: porting much easier!

That's true.  And very cool that it helps enable more technology...
