5.2.1 USB_ERROR_BUFFER_TOO_SMALL Macro

File

usb_host_android.h

#define USB_ERROR_BUFFER_TOO_SMALL USB_ERROR_CLASS_DEFINED + 0

Description

Error code indicating that the buffer passed to the read function was too small. Since the USB host can't control how much

data it will receive in a single packet, the user must provide a buffer that is at least the size of the endpoint of the attached

device. If a buffer is passed in that is too small, the read will not start and this error is returned to the user.

5.3 Configuration Definitions

Macros

Name Description

NUM_ANDROID_DEVICES_SUPPORTED

( see page 29)

Defines the number of concurrent Android devices this

implementation is allowed to talk to. This definition is only used for

implementations where the accessory is the host and the Android

device is the slave. This is also most often defined to be 1. If this

is not defined by the user, a default of 1 is used.

This option is only used when compiling the source version of the

library. This value is set to 1 for pre-compiled versions of the

library.
