TUsbEndpointDescriptor Class Reference

class TUsbEndpointDescriptor : public TUsbGenericDescriptor

Endpoint descriptor.

See section 9.6.6 of the USB 2.0 specification. Note these exclude support support for: 'Standard AC Interrupt Endpoint Descriptor' 'Standard AS Isochronous Synch Endpoint Descriptor' 'Standard AS Isochronous Audio Data Endpoint Descriptor' as defined in USB Audio Device Class Spec v1.0 which are all 9 bytes in size. To support these custom descriptors may be registered with the parser.

Intended to be available to 3rd parties later
