#include <sys/usbdi.h>

int usbd_detach( struct usbd_device *device ); 

Arguments:

device

An opaque handle from usbd_attach().

Library:

libusbdi

Description:

You use the usbd_detach() function to disconnect from a USB device that you previously had attached to via usbd_attach().

The usbd_detach() function automatically closes any pipes previously opened via usbd_open_pipe().

Returns:

EOK

Success.

EBUSY

I/O pending on the device.

Caveats:

Don't try to detach if there's I/O pending on the device. If there is, usbd_detach() will fail.
