Module capsules_extra::usb::descriptors

Platform-independent USB 2.0 protocol library.

Mostly data types for USB descriptors.

Structs

• Buffer8
• Buffer64
• CdcAcmSetLineCodingData
  The data structure sent in a CDC-ACM Set Line Coding message.
• CdcInterfaceDescriptor
• ConfigurationAttributes
• ConfigurationDescriptor
• DescriptorBuffer
  Buffer for holding the configuration, interface(s), and endpoint(s) descriptors. Also includes class-specific functional descriptors.
• DeviceBuffer
  Buffer for holding the device descriptor.
• DeviceDescriptor
• DeviceRequestType
• EndpointAddress
• EndpointDescriptor
• HIDDescriptor
• HIDSubordinateDescriptor
• InterfaceDescriptor
• LanguagesDescriptor
• ReportDescriptor
• SetupData
  The data structure sent in a SETUP handshake.
• StringDescriptor

Enums

• CdcInterfaceDescriptorSubType
• DescriptorType
• FeatureSelector
• HIDCountryCode
• Recipient
• RequestType
• StandardRequest
• TransferDirection

Traits

• Descriptor

Functions

• create_descriptor_buffers
  Transform descriptor structs into descriptor buffers that can be passed into the control endpoint handler. Each endpoint descriptor list corresponds to the matching index in the interface descriptor list. For example, if the interface descriptor list contains [ID1, ID2, ID3], and the endpoint descriptors list is [[ED1, ED2], [ED3, ED4, ED5], [ED6]], then the third interface descriptor (ID3) has one corresponding endpoint descriptor (ED6).
