/*
* Universal Serial Bus Driver/Helper Library

* Written by Filip Navara <xnavara@volny.cz>
*
* Notes:
* This driver was obsoleted in Windows XP and most functions
* became pure stubs. But some of them were retained for backward
* compatibilty with existing drivers.
*
* Preserved functions:
*
* USBD_Debug_GetHeap (implemented)
* USBD_Debug_RetHeap (implemented)
* USBD_CalculateUsbBandwidth (implemented, tested)
* USBD_CreateConfigurationRequestEx (implemented)
* USBD_CreateConfigurationRequest
* USBD_GetInterfaceLength (implemented)
* USBD_ParseConfigurationDescriptorEx (implemented)
* USBD_ParseDescriptors (implemented)
* USBD_GetPdoRegistryParameters (implemented)
