Detailed Description

This file contains the function prototypes necessary for the issuing of outgoing standard control requests when the library is in USB host mode.

Note

This file should not be included directly. It is automatically included as needed by the USB driver dispatch header located in LUFA/Drivers/USB/USB.h.

Macro Definition Documentation

#define USB_HOST_TIMEOUT_MS   1000

Constant for the maximum software timeout period of sent USB control transactions to an attached device. If a device fails to respond to a sent control request within this period, the library will return a timeout error code.

This value may be overridden in the user project makefile as the value of the USB_HOST_TIMEOUT_MS token, and passed to the compiler using the -D switch.
