# build flags with -O3 appended (so the files will build at

* behaviour included loading the built-in audio class 1.0 driver on some

* Presenting a blank configuration first prevented loading the composite driver
* and issues arising from it, while still allowing to load a vendor driver on

*
* Recent Windows subsystem can parse our class 2.0 descriptor correctly
* (certainly Windows 7 and onwards). It may be possible to remove this
