Detailed Description

EFI_USB_IO_PROTOCOL pseudo Host Controller Interface driver.

Definition in file usbio.h.

Macro Definition Documentation

◆ USBIO_MTU

#define USBIO_MTU 16384

USB I/O maximum transfer size.

The API provides no way to discover the maximum transfer size. Assume the 16kB supported by EHCI.

Definition at line 24 of file usbio.h.

◆ USBIO_INTR_COUNT

#define USBIO_INTR_COUNT 4

USB I/O interrupt ring buffer size.

This is a policy decision.

Definition at line 30 of file usbio.h.

◆ USBIO_RING_COUNT

#define USBIO_RING_COUNT 64

USB I/O ring buffer size.

This is a policy decision.

Definition at line 50 of file usbio.h.

Enumeration Type Documentation

◆ usbio_flags

enum usbio_flags

USB I/O transfer flags.

Enumerator
USBIO_MESSAGE	This is a message transfer.
USBIO_ZLEN	This transfer requires zero-length packet termination.

Definition at line 84 of file usbio.h.

                  {
         /** This is a message transfer */
         USBIO_MESSAGE = 0x01,
         /** This transfer requires zero-length packet termination */
         USBIO_ZLEN = 0x02,
 };
