-What: USB driver API moves to EXPORT_SYMBOL_GPL
-When: February 2008
-Files: include/linux/usb.h, drivers/usb/core/driver.c
-Why: The USB subsystem has changed a lot over time, and it has been
- possible to create userspace USB drivers using usbfs/libusb/gadgetfs
- that operate as fast as the USB bus allows. Because of this, the USB
- subsystem will not be allowing closed source kernel drivers to
- register with it, after this grace period is over. If anyone needs
- any help in converting their closed source drivers over to use the
- userspace filesystems, please contact the
- linux-usb-devel@lists.sourceforge.net mailing list, and the developers
- there will be glad to help you out.

+
+ Linux USB Printer Gadget Driver
+ 06/04/2007
+
+ Copyright (C) 2007 Craig W. Nadler <craig@nadler.us>
+
+
+
+GENERAL
+=======
+
+This driver may be used if you are writing printer firmware using Linux as
+the embedded OS. This driver has nothing to do with using a printer with
+your Linux host system.
+
+You will need a USB device controller and a Linux driver for it that accepts
+a gadget / "device class" driver using the Linux USB Gadget API. After the
+USB device controller driver is loaded then load the printer gadget driver.
+This will present a printer interface to the USB Host that your USB Device
+port is connected to.
+
+This driver is structured for printer firmware that runs in user mode. The
+user mode printer firmware will read and write data from the kernel mode
+printer gadget driver using a device file. The printer returns a printer status
+byte when the USB HOST sends a device request to get the printer status. The
+user space firmware can read or write this status byte using a device file
+/dev/g_printer . Both blocking and non-blocking read/write calls are supported.
+
+
+
+
+HOWTO USE THIS DRIVER
+=====================
+
+To load the USB device controller driver and the printer gadget driver. The
+following example uses the Netchip 2280 USB device controller driver:
+
+modprobe net2280
+modprobe g_printer
+
+
+The follow command line parameter can be used when loading the printer gadget
+(ex: modprobe g_printer idVendor=0x0525 idProduct=0xa4a8 ):
+
+idVendor - This is the Vendor ID used in the device descriptor. The default is
+ the Netchip vendor id 0x0525. YOU MUST CHANGE TO YOUR OWN VENDOR ID
+ BEFORE RELEASING A PRODUCT. If you plan to release a product and don't
+ already have a Vendor ID please see www.usb.org for details on how to
+ get one.
+
+idProduct - This is the Product ID used in the device descriptor. The default
+ is 0xa4a8, you should change this to an ID that's not used by any of
+ your other USB products if you have any. It would be a good idea to
+ start numbering your products starting with say 0x0001.
+
+bcdDevice - This is the version number of your product. It would be a good idea
+ to put your firmware version here.
+
+iManufacturer - A string containing the name of the Vendor.
+
+iProduct - A string containing the Product Name.
+
+iSerialNum - A string containing the Serial Number. This should be changed for
+ each unit of your product.
+
+iPNPstring - The PNP ID string used for this printer. You will want to set
+ either on the command line or hard code the PNP ID string used for
+ your printer product.
+
+qlen - The number of 8k buffers to use per endpoint. The default is 10, you
+ should tune this for your product. You may also want to tune the
+ size of each buffer for your product.
+
+
+
+
+USING THE EXAMPLE CODE
+======================
+
+This example code talks to stdout, instead of a print engine.
+
+To compile the test code below:
+
+1) save it to a file called prn_example.c
+2) compile the code with the follow command:
+ gcc prn_example.c -o prn_example
+
+
+
+To read printer data from the host to stdout:
+
+ # prn_example -read_data
+
+
+To write printer data from a file (data_file) to the host:
+
+ # cat data_file | prn_example -write_data
+
+
+To get the current printer status for the gadget driver:
+
+ # prn_example -get_status
+
+ Printer status is:
+ Printer is NOT Selected
+ Paper is Out
+ Printer OK
+
+
+To set printer to Selected/On-line:
+
+ # prn_example -selected
+
+
+To set printer to Not Selected/Off-line:
+
+ # prn_example -not_selected
+
+
+To set paper status to paper out:
+
+ # prn_example -paper_out
+
+
+To set paper status to paper loaded:
+
+ # prn_example -paper_loaded
+
+
+To set error status to printer OK:
+
+ # prn_example -no_error
+
+
+To set error status to ERROR:
+
+ # prn_example -error
+
+

+Infinity Usb Unlimited Readme
+-----------------------------
+
+Hi all,
+
+
+This module provide a serial interface to use your
+IUU unit in phoenix mode. Loading this module will
+bring a ttyUSB[0-x] interface. This driver must be
+used by your favorite application to pilot the IUU
+
+This driver is still in beta stage, so bugs can
+occur and your system may freeze. As far I now,
+I never had any problem with it, but I'm not a real
+guru, so don't blame me if your system is unstable
+
+You can plug more than one IUU. Every unit will
+have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)
+
+
+
+How to tune the reader speed ?
+
+ A few parameters can be used at load time
+ To use parameters, just unload the module if it is
+ already loaded and use modprobe iuu_phoenix param=value.
+ In case of prebuilt module, use the command
+ insmod iuu_phoenix param=value.
+
+ Example:
+
+ modprobe iuu_phoenix clockmode=3
+
+ The parameters are:
+
+ parm: clockmode:1=3Mhz579,2=3Mhz680,3=6Mhz (int)
+ parm: boost:overclock boost percent 100 to 500 (int)
+ parm: cdmode:Card detect mode 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
+ parm: xmas:xmas color enabled or not (bool)
+ parm: debug:Debug enabled or not (bool)
+
+- clockmode will provide 3 different base settings commonly adopted by
+ different software:
+ 1. 3Mhz579
+ 2. 3Mhz680
+ 3. 6Mhz
+
+- boost provide a way to overclock the reader ( my favorite :-) )
+ For example to have best performance than a simple clockmode=3, try this:
+
+ modprobe boost=195
+
+ This will put the reader in a base of 3Mhz579 but boosted a 195 % !
+ the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
+ the speed to a score 10 to 20% better than the simple clockmode=3 !!!
+
+
+- cdmode permit to setup the signal used to inform the userland ( ioctl answer )
+ if the card is present or not. Eight signals are possible.
+
+- xmas is completely useless except for your eyes. This is one of my friend who was
+ so sad to have a nice device like the iuu without seeing all color range available.
+ So I have added this option to permit him to see a lot of color ( each activity change the color
+ and the frequency randomly )
+
+- debug will produce a lot of debugging messages...
+
+
+ Last notes:
+
+ Don't worry about the serial settings, the serial emulation
+ is an abstraction, so use any speed or parity setting will
+ work. ( This will not change anything ).Later I will perhaps
+ use this settings to deduce de boost but is that feature
+ really necessary ?
+ The autodetect feature used is the serial CD. If that doesn't
+ work for your software, disable detection mechanism in it.
+
+
+ Have fun !
+

- * The prelimilary port to the 2.6 kernel was by Rus V. Brushkoff. I have
- * fixed a couple of things.
- *
- * (27/May/2004) Ian Abbott
- * Improved throttling code, mostly stolen from the WhiteHEAT driver.
- *
- * (26/Mar/2004) Jan Capek
- * Added PID's for ICD-U20/ICD-U40 - incircuit PIC debuggers from CCS Inc.
- *
- * (09/Feb/2004) Ian Abbott
- * Changed full name of USB-UIRT device to avoid "/" character.
- * Added FTDI's alternate PID (0x6006) for FT232/245 devices.
- * Added PID for "ELV USB Module UO100" from Stefan Frings.
- *
- * (21/Oct/2003) Ian Abbott
- * Renamed some VID/PID macros for Matrix Orbital and Perle Systems
- * devices. Removed Matrix Orbital and Perle Systems devices from the
- * 8U232AM device table, but left them in the FT232BM table, as they are
- * known to use only FT232BM.
- *
- * (17/Oct/2003) Scott Allen
- * Added vid/pid for Perle Systems UltraPort USB serial converters
- *
- * (21/Sep/2003) Ian Abbott
- * Added VID/PID for Omnidirectional Control Technology US101 USB to
- * RS-232 adapter (also rebadged as Dick Smith Electronics XH6381).
- * VID/PID supplied by Donald Gordon.
- *
- * (19/Aug/2003) Ian Abbott
- * Freed urb's transfer buffer in write bulk callback.
- * Omitted some paranoid checks in write bulk callback that don't matter.
- * Scheduled work in write bulk callback regardless of port's open count.
- *
- * (05/Aug/2003) Ian Abbott
- * Added VID/PID for ID TECH IDT1221U USB to RS-232 adapter.
- * VID/PID provided by Steve Briggs.
- *
- * (23/Jul/2003) Ian Abbott
- * Added PIDs for CrystalFontz 547, 633, 631, 635, 640 and 640 from
- * Wayne Wylupski.
- *
- * (10/Jul/2003) David Glance
- * Added PID for DSS-20 SyncStation cradle for Sony-Ericsson P800.
- *
- * (27/Jun/2003) Ian Abbott
- * Reworked the urb handling logic. We have no more pool, but dynamically
- * allocate the urb and the transfer buffer on the fly. In testing this
- * does not incure any measurable overhead. This also relies on the fact
- * that we have proper reference counting logic for urbs. I nicked this
- * from Greg KH's Visor driver.
- *
- * (23/Jun/2003) Ian Abbott
- * Reduced flip buffer pushes and corrected a data length test in
- * ftdi_read_bulk_callback.
- * Defererence pointers after any paranoid checks, not before.
- *
- * (21/Jun/2003) Erik Nygren
- * Added support for Home Electronics Tira-1 IR transceiver using FT232BM chip.
- * See <http://www.home-electro.com/tira1.htm>. Only operates properly
- * at 100000 and RTS-CTS, so set custom divisor mode on startup.
- * Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
- *
- * (18/Jun/2003) Ian Abbott
- * Added Device ID of the USB relais from Rudolf Gugler (backported from
- * Philipp Gühring's patch for 2.5.x kernel).
- * Moved read transfer buffer reallocation into startup function.
- * Free existing write urb and transfer buffer in startup function.
- * Only use urbs in write urb pool that were successfully allocated.
- * Moved some constant macros out of functions.
- * Minor whitespace and comment changes.
- *
- * (12/Jun/2003) David Norwood
- * Added support for USB-UIRT IR transceiver using 8U232AM chip.
- * See <http://home.earthlink.net/~jrhees/USBUIRT/index.htm>. Only
- * operates properly at 312500, so set custom divisor mode on startup.
- *
- * (12/Jun/2003) Ian Abbott
- * Added Sealevel SeaLINK+ 210x, 220x, 240x, 280x vid/pids from Tuan Hoang
- * - I've eliminated some that don't seem to exist!
- * Added Home Electronics Tira-1 IR transceiver pid from Chris Horn
- * Some whitespace/coding-style cleanups
- *
- * (11/Jun/2003) Ian Abbott
- * Fixed unsafe spinlock usage in ftdi_write
- *
- * (24/Feb/2003) Richard Shooter
- * Increase read buffer size to improve read speeds at higher baud rates
- * (specifically tested with up to 1Mb/sec at 1.5M baud)
- *
- * (23/Feb/2003) John Wilkins
- * Added Xon/xoff flow control (activating support in the ftdi device)
- * Added vid/pid for Videonetworks/Homechoice (UK ISP)
- *
- * (23/Feb/2003) Bill Ryder
- * Added matrix orb device vid/pids from Wayne Wylupski
- *
- * (19/Feb/2003) Ian Abbott
- * For TIOCSSERIAL, set alt_speed to 0 when ASYNC_SPD_MASK value has
- * changed to something other than ASYNC_SPD_HI, ASYNC_SPD_VHI,
- * ASYNC_SPD_SHI or ASYNC_SPD_WARP. Also, unless ASYNC_SPD_CUST is in
- * force, don't bother changing baud rate when custom_divisor has changed.
- *
- * (18/Feb/2003) Ian Abbott
- * Fixed TIOCMGET handling to include state of DTR and RTS, the state
- * of which are now saved by set_dtr() and set_rts().
- * Fixed improper storage class for buf in set_dtr() and set_rts().
- * Added FT232BM chip type and support for its extra baud rates (compared
- * to FT8U232AM).
- * Took account of special case divisor values for highest baud rates of
- * FT8U232AM and FT232BM.
- * For TIOCSSERIAL, forced alt_speed to 0 when ASYNC_SPD_CUST kludge used,
- * as previous alt_speed setting is now stale.
- * Moved startup code common between the startup routines for the
- * different chip types into a common subroutine.
- *
- * (17/Feb/2003) Bill Ryder
- * Added write urb buffer pool on a per device basis
- * Added more checking for open file on callbacks (fixed OOPS)
- * Added CrystalFontz 632 and 634 PIDs
- * (thanx to CrystalFontz for the sample devices - they flushed out
- * some driver bugs)
- * Minor debugging message changes
- * Added throttle, unthrottle and chars_in_buffer functions
- * Fixed FTDI_SIO (the original device) bug
- * Fixed some shutdown handling
- *
- *
- *
- *
- * (07/Jun/2002) Kuba Ober
- * Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor
- * function. It was getting too complex.
- * Fix the divisor calculation logic which was setting divisor of 0.125
- * instead of 0.5 for fractional parts of divisor equal to 5/8, 6/8, 7/8.
- * Also make it bump up the divisor to next integer in case of 7/8 - it's
- * a better approximation.
- *
- * (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch
- * Not tested by me but it doesn't break anything I use.
- *
- * (04/Jan/2002) Kuba Ober
- * Implemented 38400 baudrate kludge, where it can be substituted with other
- * values. That's the only way to set custom baudrates.
- * Implemented TIOCSSERIAL, TIOCGSERIAL ioctl's so that setserial is happy.
- * FIXME: both baudrate things should eventually go to usbserial.c as other
- * devices may need that functionality too. Actually, it can probably be
- * merged in serial.c somehow - too many drivers repeat this code over
- * and over.
- * Fixed baudrate forgetfulness - open() used to reset baudrate to 9600 every time.
- * Divisors for baudrates are calculated by a macro.
- * Small code cleanups. Ugly whitespace changes for Plato's sake only ;-].
- *
- * (04/Nov/2001) Bill Ryder
- * Fixed bug in read_bulk_callback where incorrect urb buffer was used.
- * Cleaned up write offset calculation
- * Added write_room since default values can be incorrect for sio
- * Changed write_bulk_callback to use same queue_task as other drivers
- * (the previous version caused panics)
- * Removed port iteration code since the device only has one I/O port and it
- * was wrong anyway.
- *
- * (31/May/2001) gkh
- * Switched from using spinlock to a semaphore, which fixes lots of problems.
- *
- * (23/May/2001) Bill Ryder
- * Added runtime debug patch (thanx Tyson D Sawyer).
- * Cleaned up comments for 8U232
- * Added parity, framing and overrun error handling
- * Added receive break handling.
- *
- * (04/08/2001) gb
- * Identify version on module load.
- *
- * (18/March/2001) Bill Ryder
- * (Not released)
- * Added send break handling. (requires kernel patch too)
- * Fixed 8U232AM hardware RTS/CTS etc status reporting.
- * Added flipbuf fix copied from generic device
- *
- * (12/3/2000) Bill Ryder
- * Added support for 8U232AM device.
- * Moved PID and VIDs into header file only.
- * Turned on low-latency for the tty (device will do high baudrates)
- * Added shutdown routine to close files when device removed.
- * More debug and error message cleanups.
- *
- * (11/13/2000) Bill Ryder
- * Added spinlock protected open code and close code.
- * Multiple opens work (sort of - see webpage mentioned above).
- * Cleaned up comments. Removed multiple PID/VID definitions.
- * Factorised cts/dtr code
- * Made use of __FUNCTION__ in dbg's
- *
- * (11/01/2000) Adam J. Richter
- * usb_device_id table support
- *
- * (10/05/2000) gkh
- * Fixed bug with urb->dev not being set properly, now that the usb
- * core needs it.
- *
- * (09/11/2000) gkh
- * Removed DEBUG #ifdefs with call to usb_serial_debug_data
- *
- * (07/19/2000) gkh
- * Added module_init and module_exit functions to handle the fact that this
- * driver is a loadable module now.
- *
- * (04/04/2000) Bill Ryder
- * Fixed bugs in TCGET/TCSET ioctls (by removing them - they are
- * handled elsewhere in the tty io driver chain).
- *
- * (03/30/2000) Bill Ryder
- * Implemented lots of ioctls
- * Fixed a race condition in write
- * Changed some dbg's to errs
- *
- * (03/26/2000) gkh
- * Split driver up into device specific pieces.
+ * Change entries from 2004 and earlier can be found in versions of this
+ * file in kernel versions prior to the 2.6.24 release.
