Field Documentation

usb_alternate_interfaces_t* alternate_interfaces

Alternative interfaces.

Set to NULL when the driver controls whole device (i.e. more (or any) interfaces).

Definition at line 93 of file driver.h.

void* driver_data

Custom driver data.

Do not use the entry in generic device, that is already used by the framework.

Definition at line 104 of file driver.h.

int interface_no

Current interface.

Usually, drivers operate on single interface only. This item contains the value of the interface or -1 for any.

Definition at line 87 of file driver.h.

usb_endpoint_mapping_t* pipes

Other endpoint pipes.

This is an array of other endpoint pipes in the same order as in usb_driver_t.

Definition at line 80 of file driver.h.

usb_device_connection_t wire

Connection backing the pipes.

Typically, you will not need to use this attribute at all.

Definition at line 109 of file driver.h.
