* The use of two configurations dates back to Windows XP (could be SP2). This
* lacked some standards support and incorrectly parsed the full audio class 2.0
* descriptor with its IADs (Interface Association Descriptors). The observed
* behaviour included loading the built-in audio class 1.0 driver on some
* interfaces (possibly the wrong ones, too), and hanging.
*
* Presenting a blank configuration first prevented loading the composite driver
* and issues arising from it, while still allowing to load a vendor driver on
* the actual configuration.
*
* Recent Windows subsystem can parse our class 2.0 descriptor correctly
* (certainly Windows 7 and onwards). It may be possible to remove this
