Enumeration Type Documentation
| enum usb_descriptor_type |
Standard USB descriptor types.
Definition at line 144 of file usb_protocol.h.
| enum usb_device_feature |
Standard USB device feature/status flags.
Definition at line 118 of file usb_protocol.h.
| enum usb_device_speed |
USB device speed. USB_SPEED_UNKNOWN indicates that the device has not yet seen a reset (i.e. it is in the POWERED or the ATTACHED state, possibly suspended.)
Definition at line 72 of file usb_protocol.h.
| enum usb_device_state |
USB device state. See the device state diagram in the USB 2.0 specification for more information.
Definition at line 53 of file usb_protocol.h.
| enum usb_endpoint_feature |
Standard USB endpoint feature/status flags.
Definition at line 126 of file usb_protocol.h.
| enum usb_recipient |
Possible USB recipient codes (bmRequestType).
Definition at line 91 of file usb_protocol.h.
| enum usb_reqid |
Standard USB requests (bRequest).
Definition at line 101 of file usb_protocol.h.
| enum usb_reqtype |
Possible USB request types (bmRequestType).
Definition at line 82 of file usb_protocol.h.
Standard USB Test Mode Selectors
Definition at line 133 of file usb_protocol.h.
Variable Documentation
| struct usb_endpoint_descriptor __packed |
A USB Device request. The data payload of SETUP packets always follows this structure.
Standard USB device descriptor.
Standard USB device qualifier descriptor. This contains information about the device when running at the "other" speed (i.e. if the device is currently operating at high speed, this descriptor can be used to determine what would change if the device was operating at full speed.)
Standard USB configuration descriptor.
Standard USB interface descriptor.
Standard USB endpoint descriptor.
