.Sh DESCRIPTION
|
|
Device driver access to the USB bus centers around transfers.
|
|
A transfer describes a communication with a USB device.
|
|
A transfer is an abstract concept that can result in several
|
|
physical packets being transferred to or from a device.
|
|
A transfer is described by a
|
|
.Va usbd_xfer_handle .
|
|
It is allocated by
|
|
.Va usbd_alloc_xfer
|
|
and the data describing the transfer is filled by
|
|
.Va usbd_setup_default_xfer
|
|
for control pipe transfers, by
|
|
.Va usbd_setup_xfer
|
|
for bulk and interrupt transfers, and by
|
|
.Va usbd_setup_isoc_xfer
|
|
for isochronous transfers.

.Sh HISTORY
|
|
This
|
|
.Nm
|
|
interface first appeared in
|
|
.Nx 1.4 .
|
|
The interface is based on an early definition from the OpenUSBDI group
|
|
within the USB organisation.
|
|
Right after this definition the OpenUSBDI development got closed for open
|
|
source developers, so this interface has not followed the further changes.
|
|
The OpenUSBDI specification is now available again, but looks different.
|
|
.Sh BUGS
|
|
This man page is under development, so its biggest shortcoming is
|
|
incompleteness.
