-The EEPROM on the DUART28 adapter board has two valid configurations: DUART28C
-and DUART28S.  As of this writing the S configuration is the default shipping
-one, but this situation may change in the future.  The difference between the
-two configs is in the USB VID:PID presented by the USB device, and this USB ID
-difference has the following practical impact:
-
-* The C configuration presents a custom USB ID and requires a custom patch to
-  the Linux kernel ftdi_sio driver in order to work - without this ftdi_sio
-  driver patch it won't work at all.  But if you do go through the pain of
-  applying the needed patch to your Linux kernel ftdi_sio driver, the reward
-  is that you get not only the two Calypso UARTs, but also working boot control
-  outputs.
-
-* The S configuration presents the default FT2232x USB ID and is therefore
-  supported out of the box by the standard Linux ftdi_sio driver without needing
-  any patches.  However, the adapter's CTL1 and CTL2 outputs cannot be used in
-  this configuration (they will be bogusly asserted whenever Channel B ttyUSB
-  device is opened), and thus they must be left unconnected, and you don't get
-  to play with the remote boot control feature.
-
-The physical hardware is identical between the two configurations, only the
-EEPROM programming changes, thus end users need to be able to switch freely
-between the two EEPROM configs as they wish.  This article explains how to
-program the EEPROM back and forth between the two configs.

-Determining your current DUART28 config
-=======================================
-
-Connect the USB cable between your DUART28 board and your Linux host, and
-observe dmesg output.  If your DUART28 board is in the C configuration, it will
-present as USB ID 0403:7152, and if it is in the S config, it will present as
-USB ID 0403:6010.  You can also see these USB IDs with lsusb.  The product ID
-string is also programmed as "DUART28C" or "DUART28S".

-Converting from DUART28S to DUART28C
-====================================
-
-If your DUART28 board is currently in the S config, its USB ID will be
-0403:6010, which is the default ID for FTDI's two-channel FT2232x family.
-Because it is the standard default, there are plenty of other gadgets using the
-same ID - thus you need to ensure that you have no other USB devices with the
-same ID connected to your system during the reprogramming operation.  Run lsusb
-and ensure that you see only one USB device with ID 0403:6010.  Ensure that this
-one device really is your DUART28 board: unplug that USB cable and make sure
-that the device disappears, plug it back in and make sure that it reappears.
-
-One you have confirmed that you won't inadvertently hit some other FT2232x
-device, execute the actual programming command as follows (from the top
-directory of this code repository):
-
-ftee-gen2232c eeproms/duart28c $Serial | fteeprom-prog i:0x0403:0x6010
-
-(See FTDI-EEPROM-tools article for other ways to specify the target device to
- fteeprom-prog.)
-
-Replace the $Serial metavariable with the 3-digit serial number of your DUART28
-adapter board as it appears on the factory serial number sticker.
-
-After this operation completes successfully, unplug and replug the USB cable
-between the DUART28 board and your host - the adapter should now show up with
-USB ID 0403:7152.
-
-Converting from DUART28C to DUART28S
-====================================
-
-If your DUART28 board is currently in the C config, its USB ID will be
-0403:7152, which is a private ID that belongs to us and should not be used by
-other parties.  The reverse conversion command is as follows:
-
-ftee-gen2232c eeproms/duart28s $Serial | fteeprom-prog i:0x0403:0x7152
