Can you add the USB IDs for the Belkin USB Serial adapter (P/N F5U257)

to approach for this?
I recently purchased a Belkin USB Serial adapter (P/N F5U257) and found
that it didn't work. After a bit of experimentation I found that it
works with the pl2303 driver once the ID has been added. See attached

"SHARP WS003SH" has two modes, "Modem" and "ActiveSync".
But, "ActiveSync" mode uses NDIS connection.

The below patch fixes the ipw module in kernel 2.6.17 for me; without
this change it simply does not work at all (all but the first writes are
refused because write_urb_busy is always 1).
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.

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.

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!).

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.)

Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels
to prevent the N_TTY line discipline functions read_chan() and
n_tty_receive_buf() from running at the same time. 2.2.15 introduced
tty->read_lock to protect access to the N_TTY read buffer, which is the
only state requiring protection between these two functions.
The current TTY_DONT_FLIP implementation is broken for SMP, and is not
universally honored by drivers that send data directly to the line
discipline receive_buf function.
Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is
not universally honored, it is removed.

The API and code have been through various bits of initial review by
serial driver people but they definitely need to live somewhere for a
while so the unconverted drivers can get knocked into shape, existing
drivers that have been updated can be better tuned and bugs whacked out.
This replaces the tty flip buffers with kmalloc objects in rings. In the
normal situation for an IRQ driven serial port at typical speeds the
behaviour is pretty much the same, two buffers end up allocated and the
kernel cycles between them as before.
When there are delays or at high speed we now behave far better as the
buffer pool can grow a bit rather than lose characters. This also means
that we can operate at higher speeds reliably.
For drivers that receive characters in blocks (DMA based, USB and
especially virtualisation) the layer allows a lot of driver specific
code that works around the tty layer with private secondary queues to be
removed. The IBM folks need this sort of layer, the smart serial port
people do, the virtualisers do (because a virtualised tty typically
operates at infinite speed rather than emulating 9600 baud).
Finally many drivers had invalid and unsafe attempts to avoid buffer
overflows by directly invoking tty methods extracted out of the innards
of work queue structs. These are no longer needed and all go away. That
fixes various random hangs with serial ports on overflow.
The other change in here is to optimise the receive_room path that is
used by some callers. It turns out that only one ldisc uses receive room
except asa constant and it updates it far far less than the value is
read. We thus make it a variable not a function call.
I expect the code to contain bugs due to the size alone but I'll be
watching and squashing them and feeding out new patches as it goes.
Because the buffers now dynamically expand you should only run out of
buffering when the kernel runs out of memory for real. That means a lot of
the horrible hacks high performance drivers used to do just aren't needed any
more.
Description:
tty_insert_flip_char is an old API and continues to work as before, as does
tty_flip_buffer_push() [this is why many drivers dont need modification]. It
does now also return the number of chars inserted
There are also
tty_buffer_request_room(tty, len)
which asks for a buffer block of the length requested and returns the space
found. This improves efficiency with hardware that knows how much to
transfer.
and tty_insert_flip_string_flags(tty, str, flags, len)
to insert a string of characters and flags
For a smart interface the usual code is
len = tty_request_buffer_room(tty, amount_hardware_says);
tty_insert_flip_string(tty, buffer_from_card, len);
More description!
At the moment tty buffers are attached directly to the tty. This is causing a
lot of the problems related to tty layer locking, also problems at high speed
and also with bursty data (such as occurs in virtualised environments)
I'm working on ripping out the flip buffers and replacing them with a pool of
dynamically allocated buffers. This allows both for old style "byte I/O"
devices and also helps virtualisation and smart devices where large blocks of
data suddenely materialise and need storing.
So far so good. Lots of drivers reference tty->flip.*. Several of them also
call directly and unsafely into function pointers it provides. This will all
break. Most drivers can use tty_insert_flip_char which can be kept as an API
but others need more.
At the moment I've added the following interfaces, if people think more will
be needed now is a good time to say
int tty_buffer_request_room(tty, size)
Try and ensure at least size bytes are available, returns actual room (may be
zero). At the moment it just uses the flipbuf space but that will change.
Repeated calls without characters being added are not cumulative. (ie if you
call it with 1, 1, 1, and then 4 you'll have four characters of space. The
other functions will also try and grow buffers in future but this will be a
more efficient way when you know block sizes.
int tty_insert_flip_char(tty, ch, flag)
As before insert a character if there is room. Now returns 1 for success, 0
for failure.
int tty_insert_flip_string(tty, str, len)
Insert a block of non error characters. Returns the number inserted.
int tty_prepare_flip_string(tty, strptr, len)
Adjust the buffer to allow len characters to be added. Returns a buffer
pointer in strptr and the length available. This allows for hardware that
needs to use functions like insl or mencpy_fromio.

ftdi_sio: Avoid losing bytes at tty-ldisc.
This patch was originally developed by Daniel Smertnig. I
(Ian Abbott) made a few changes. It has been tested by both
Daniel and I, at least for raw, non-canonical receive data
processing.
Here is Daniel's original description of the patch:
===
During a project in which I was using a FTDI 232BM to
transmit data at relative high speeds (625kBit/s), I
noticed a problem where data was lost even if flow
control was enabled: The FTDI-Driver receives 512 Bytes
of data over USB at a time, which consists of 8 64-Byte
packets. Subtracting the 2 bytes of status information
included in each packet this gives 496 "real" data
bytes per read.
This data is passed (indirectly, via the flip buffers)
to the tty line discipline which takes care of
throttling when there the free buffer space reaches
TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver
processes up to 496 bytes at a time, throttling won't
happen in time and the line discipline will discard the
remaining bytes.
To avoid this the patch passes data in 62-byte blocks
to the tty layer and checks the available space in the
ldisc-buffers. If there isn't enough free space,
processing the rest of the data is delayed using a
workqueue.
Note: The original problem should be easily
reproducible with a userspace program which does slow &
small reads.

Traditionally, this card has been accessed via the standard serial driver

Get rid of a bunch of redundant NULL pointer checks in drivers/usb/*,
there's no need to check a pointer for NULL before calling kfree() on it.

Here's a tiny patch to add support for the Tapwave Zodiac (for
2.6.11.6). I've been meaning to send it in for a while but kept
upgrading my kernel and losing the changes :-) I own the device and it
works fine with the latest pilot-link beta.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
