Module cyme::usb

Defines for USB, mainly thosed covered at usb.org

Also refering to beyondlogic

There are some repeated/copied Enum defines from rusb in order to control Serialize/Deserialize and add impl

Structs

• EndpointAddress
  Address information for a USBEndpoint
• USBConfiguration
  Devices can have multiple configurations, each with different attributes and interfaces
• USBDeviceExtra
  Extra USB device data for verbose printing
• USBEndpoint
  Endpoint for a USBInterface
• USBInterface
  Interface within a USBConfiguration
• Version
  The version value (for BCD and USB) is in binary coded decimal with a format of 0xJJMN where JJ is the major version number, M is the minor version number and N is the sub minor version number. e.g. USB 2.0 is reported as 0x0200, USB 1.1 as 0x0110 and USB 1.0 as 0x0100. The type is a mirror of the one from rusb in order to impl Display, From etc.

Enums

• ClassCode
  USB class code defines ref
• ConfigAttributes
  Configuration attributes
• DescriptorUsage
  Explains how the ClassCode is used
• Direction
  Transfer and USBEndpoint direction
• Speed
  USB Speed is also defined in libusb but this one allows us to provide updates and custom impl
• SyncType
  Isochronous synchronization mode for USBEndpoint
• TransferType
  Transfer type for USBEndpoint
• UsageType
  Isochronous usage type for USBEndpoint

Functions

• get_dev_path
  Build replica of Linux dev path from libusb.c *devbususb for getting device with -D
• get_interface_path
  Build replica of sysfs path with interface
• get_parent_path
  Parent path is path to parent device
• get_port_path
  Builds a replica of sysfs path; excludes config.interface
• get_trunk_path
  Trunk path is path to trunk device on bus
