Kernel version 2.6.13 introduced a regression in the generic USB
serial converter driver (usbserial.o, drivers/usb/serial/generic.c).
The bug manifests, as far as I can tell, whenever you attempt to write
to the device -- the write will never complete (write() returns 0, or
blocks).

I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for
a bar code reader). Detecting the baudrate of the serial-IR involves
keeping DTR low while changing baudrate.
This works using normal 16550A serial ports as well as the FTDI driver
version 1.4.0 (Linux 2.6.8) but stopped working with the change to
"ensure RTS and DTR are raised when changing baudrate" introduced in
version 1.4.1 (Linux 2.6.9).
The attached patch fixes this, so RTS and DTR is only raised when
changing baudrate iff the previous baudrate was B0.

This patch for the ftdi_sio driver adds a bunch of new devices and fixes
an incorrect PID:
o Fix PID for ELV UO100 (the PID was in fact for ELV UR100).
o Add PID ELV UR100 (see above) and ELV ALC 8500 Expert.
o Add a whole bunch of other PIDs for ELV USB devices, commented out for
now as they may be used by other drivers eventually. (Christian Abt
of ELV.de submitted a full list of devices including an indication of
which set of drivers are used by default in the MS Windows world. We
decided to comment out the devices that use FTDI's D2XX Windows
drivers by default.)
o Add PIDs for eight devices from Xsens Technologies BV (submitted in a
patch against 2.6.12.2 by Patrick Riphagen).
o Add PID for Falcom Samba GPRS modem (submitted by Sebastian Schubert).

This trivial patch makes pl2303 driver work correctly with pl2303HX chip.
Apparently some bug in HX version of pl2303 makes the chip loose some
transmitted bytes or stop working at all after reception of
USB_REQ_CLEAR_FEATURE mesage. Logs generated by UsbSnoop application reveal
that windows driver does not send this type of messages to the converter.

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.

This patch adds a new driver for "Option" cards. This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card. It's sold by several GSM service
providers.
Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options. However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.
Therefore, I've written a separate driver.

Fixed problem where setting or retreiving the serial config would fail
with EPIPE. Removed CRTS toggling so the driver behaves more like other
usbserial adapters. Issued new interval of 1ms instead of the default
bInterval. As a result, transfer speed has been substantially
increased. From avg. 850bps to avg. 3300bps. Also added new module
parameter 'interval' to tweak the interval in case this change causes
problems for someone. Cleaned up code and formatting issues so source
is more readable. Replaced the C++ style comments. Various other code
cleanups.

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!
