<title>USB Devices</title>
<para>Drivers for USB devices talk to the "usbcore" APIs, and are
exposed through driver frameworks such as block, character,
or network devices.
There are two types of public "usbcore" APIs: those intended for
general driver use, and those which are only public to drivers that
are part of the core.
The drivers that are part of the core are involved in managing a USB bus.
They include the "hub" driver, which manages trees of USB devices, and
several different kinds of "host controller" driver (HCD), which control
individual busses.
</para>
<para>The device model seen by USB drivers is relatively complex.
</para>
<itemizedlist>
<listitem><para>USB supports four kinds of data transfer
(control, bulk, interrupt, and isochronous). Two transfer
types use bandwidth as it's available (control and bulk),
while the other two types of transfer (interrupt and isochronous)
are scheduled to provide guaranteed bandwidth.
</para></listitem>
<listitem><para>The device description model includes one or more
"configurations" per device, only one of which is active at a time.
</para></listitem>
<listitem><para>Configurations have one or more "interface", each
of which may have "alternate settings". Interfaces may be
standardized by USB "Class" specifications, or may be specific to
a vendor or device.</para>
<para>USB device drivers actually bind to interfaces, not devices.
Think of them as "interface drivers", though you
may not see many devices where the distinction is important.
Most USB devices are simple, with only one configuration,
one interface, and one alternate setting.
</para></listitem>
<listitem><para>Interfaces have one or more "endpoints", each of
which supports one type and direction of data transfer such as
"bulk out" or "interrupt in". The entire configuration may have
up to sixteen endpoints in each direction, allocated as needed
among all the interfaces.
</para></listitem>
<listitem><para>Data transfer on USB is packetized; each endpoint
has a maximum packet size.
Drivers must often be aware of conventions such as flagging the end
of bulk transfers using "short" (including zero length) packets.
</para></listitem>
<listitem><para>The Linux USB API supports synchronous calls for
control and bulk messaging.
It also supports asynchnous calls for all kinds of data transfer,
using request structures called "URBs" (USB Request Blocks).
</para></listitem>
</itemizedlist>
<para>Accordingly, the USB Core API exposed to device drivers
covers quite a lot of territory. You'll probably need to consult
the USB 2.0 specification, available online from www.usb.org at
no cost, as well as class or device specifications.

Change History
Wed Feb 19 22:00:00 PST 2003 (Jeffrey S. Laing <keyspan@jsl.com>)
Merged the current (1/31/03) Keyspan code with the current (2.4.21-pre4)
Linux source tree. The Linux tree lacked support for the 49WLC and
others. The Keyspan patches didn't work with the current kernel.
2003jan30 LPM add support for the 49WLC and MPR
Wed Apr 25 12:00:00 PST 2002 (Keyspan)
Started with Hugh Blemings' code dated Jan 17, 2002. All adapters
now supported (including QI and QW). Modified port open, port
close, and send setup() logic to fix various data and endpoint
synchronization bugs and device LED status bugs. Changed keyspan_
write_room() to accurately return transmit buffer availability.
Changed forwardingLength from 1 to 16 for all adapters.
Fri Oct 12 16:45:00 EST 2001
Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV)
