a14848275b USB: add SeaLevel 2106 SeaLINK support to ftdi_sio
We have a couple of these USB-Serial converters around; they're slightly
different from the 2104 models in that they can handle 500Kb/sec over RS422.
The existing ftdi driver seems to work just fine if we add in the 
appropriate IDs.

Patch is against 2.6.17.6, but should apply cleanly to pretty much 
anything recent.

9978f9e124 USB serial ftdi_sio: Add support for Tactrix OpenPort devices
This patch adds support for three OpenPort ECU data cables from Tactrix
Inc. to the ftdi_sio driver's device ID table.  One of the PIDs was
supplied by Donour Sizemore on the ftdi-usb-sio-devel mailing list.  The
other two were added by myself after examining the Windows driver software.

5dda171202 USB: Airprime driver improvements to allow full speed EvDO transfers
Adapted from an earlier patch by Greg KH <gregkh@suse.de>.
That patch added multiple read urbs and larger transfer buffers to allow
data transfers at full EvDO speed.

This version includes additional device IDs and fixes a memory leak in
the transfer buffer allocation.

Some (maybe all?) of the supported devices present multiple bulk endpoints,
the additional EPs can be used for control and status functions,
This version allocates 3 EPs by default, that can be changed using
the 'endpoints' module parameter.

Tested with Sierra Wireless EM5625 and MC5720 embedded modules.

Device ID (0x0c88, 0x17da) for the Kyocera Wireless KPC650/Passport
was added but is not yet tested.

78aef519ed cypress_m8: implement graceful failure handling
When receiving a fatal error from the USB core, e.g. EILSEQ (which can
happen if the polling interval is too short), fail gracefully.
Previously the driver would fill the log with useless error messages
or (more alarmingly) silently spin forever trying to write updated
control information to the device.  This change implements a new flag
which if cleared indicates that the driver has failed.  The flag will
be set on initialization, cleared on fatal errors, and anything else
that touches the USB port in the driver will abort if the flag is
clear.  When the flag is cleared, a message will be logged indicating
that the driver has failed.

9aa8dae7b1 cypress_m8: use usb_fill_int_urb where appropriate
Rather than directly filling in URB fields, it's safer to use
usb_fill_int_urb().  This improves robustness of the driver; URB
changes in the future will not go uninitialized here.  That point not
withstanding, this driver should at least be self-consistent.  Either
use usb_fill_int_urb() everywhere or don't bother with it all.

0257fa9ffe cypress_m8: use appropriate URB polling interval
The polling interval for the device can't always be 1msec.  If it is
too quick, the device can fail causing a fatal (to the driver) EILSEQ
error from the USB core.  The actual correct value is reported by the
device as part of its configuration data, so use that value as the
default.  On a DeLorme Earthmate for example, the device reports that
it wants a 6msec interval.  As part of this fix, the "interval" module
option has been fixed as well; the device's default can be overridden
by specifying interval=<value> as a module option.

This problem was there in 2.6.15 as well, but at that point I used the
(updated) ipw.c, version 0.4, from
http://www.neology.co.za/products/opensource/ipwireless/ which no longer
compiles with 2.6.17. It can be made to after a few changes but
obviously it's easier if the built-in ipw driver works instead of having
to download one from the neology site.

b33488eb5c [PATCH] USB: ipaq.c timing parameters
Adds configurable waiting periods to the ipaq connection code. These are
not needed when the pocketpc device is running normally when plugged in,
but they need extra delays if they are physically connected while
rebooting.

There are two parameters :

* initial_wait : this is the delay before the driver attemts to start the
  connection. This is needed because the pocktpc device takes much
  longer to boot if the driver starts sending control packets too soon.

* connect_retries : this is the number of times the control urb is
  retried before finally giving up. The patch also adds a 1 second delay
  between retries.

I'm not sure if the cases where this patch is useful are general enough
to include this in the kernel.

224654004c [PATCH] USB serial ftdi_sio: Prevent userspace DoS
This patch limits the amount of outstanding 'write' data that can be
queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or
simple accidents) that use up all the system memory by writing lots of
data to the serial port.

The original patch was by Guillaume Autran, who in turn based it on the
same mechanism implemented in the 'visor' driver.  I (Ian Abbott)
re-targeted the patch to the latest sources, fixed a couple of errors,
renamed his new structure members, and updated the implementations of
the 'write_room' and 'chars_in_buffer' methods to take account of the
number of outstanding 'write' bytes.  It seems to work fine, though at
low baud rates it is still possible to queue up an amount of data that
takes an age to shift (a job for another day!).

00d6058ac9 [PATCH] USB serial visor: fix race in open/close
The anti user-DoS mechanism in the USB serial 'visor' driver can fail in
the following way:

visor_open: priv->outstanding_urbs = 0
visor_write: ++priv->outstanding_urbs
visor_close:
visor_open: priv->outstanding_urbs = 0
visor_write_bulk_callback: --priv->outstanding_urbs

So priv->outstanding_urbs ends up as (unsigned long)(-1).  Not good!

I haven't seen this happen with the visor driver as I don't have the
hardware, but I have seen it while testing a patch to implement the same
functionality in the ftdi_sio driver (patch not yet submitted).

The fix is pretty simple: don't reinitialize outstanding_urbs in
visor_open.  (Again, I haven't tested the fix in visor, but I have
tested it in ftdi_sio.)

3b92847425 [PATCH] USB: Support for Susteen Datapilot Universal-2 cable in pl2303
The Susteen Datapilot cable
(http://www.susteen.com/productdetail/71/producthl/Notempty) has an
internal pl2303 to communicate with a set of dummy connector-ends that
connect to a variety of cell phones. I've found that it works right out
of the box by simply adding the product/vendor id to the pl2303 driver.

bd97c4f035 [PATCH] USB: fix visor leaks
This patch fixes blatant leaks in visor driver and makes it report
mode sensible things in ->write_room (this is only needed if your visor
is a terminal though).

It is made to fit into 80 columns with a temporary variable.
Might even save a few instructions...
