/*
* This driver handles the USB Device Controller (UDC) in Intel's PXA 2xx
* series processors. The UDC for the IXP 4xx series is very similar.
* There are fifteen endpoints, in addition to ep0.
*
* Such controller drivers work with a gadget driver. The gadget driver
* returns descriptors, implements configuration and data protocols used
* by the host to interact with this device, and allocates endpoints to
* the different protocol interfaces. The controller driver virtualizes
* usb hardware so that the gadget drivers will be more portable.
*
*
* This UDC hardware wants to implement a bit too much USB protocol, so
* it constrains the sorts of USB configuration change events that work.
* The errata for these chips are misleading; some "fixed" bugs from
* pxa250 a0/a1 b0/b1/b2 sure act like they're still there.

*
* History
*
* 0.1 8/31/1999
*
* Developed/tested using linux-2.3.15 with minor ohci.c changes to
* support short packets during bulk xfer mode. Some testing was
* done with ohci-hcd but the performance was low. Very limited
* testing was performed with uhci but I was unable to get it to
* work. Initial relase to the linux-usb development effort.
*
*
* 0.2 10/16/1999
*
* - Device can't be opened unless a scanner is plugged into the USB.
* - Finally settled on a reasonable value for the I/O buffer's.
* - Cleaned up write_scanner()
* - Disabled read/write stats
* - A little more code cleanup
*
*
* 0.3 10/18/1999
*
* - Device registration changed to reflect new device
* allocation/registration for linux-2.3.22+.
* - Adopted David Brownell's <david-b@pacbell.net> technique for
* assigning bulk endpoints.
* - Removed unnecessary #include's
* - Scanner model now reported via syslog INFO after being detected
* *and* configured.
* - Added user specified vendor:product USB ID's which can be passed
* as module parameters.
*
*
* 0.3.1
*
* - Applied patches for linux-2.3.25.
* - Error number reporting changed to reflect negative return codes.
*
*
* 0.3.2
*
* - Applied patches for linux-2.3.26 to scanner_init().
* - Debug read/write stats now report values as signed decimal.
*
*
* 0.3.3
*
* - Updated the bulk_msg() calls to usb usb_bulk_msg().
* - Added a small delay in the write_scanner() method to aid in
* avoiding NULL data reads on HP scanners. We'll see how this works.
* - Return values from usb_bulk_msg() now ignore positive values for
* use with the ohci driver.
* - Added conditional debugging instead of commenting/uncommenting
* all over the place.
* - kfree()'d the pointer after using usb_string() as documented in
* linux-usb-api.txt.
* - Added usb_set_configuration(). It got lost in version 0.3 -- ack!
* - Added the HP 5200C USB Vendor/Product ID's.
*
*
* 0.3.4 1/23/2000
*
* - Added Greg K-H's <greg@kroah.com> patch for better handling of
* Product/Vendor detection.
* - The driver now autoconfigures its endpoints including interrupt
* endpoints if one is detected. The concept was originally based
* upon David Brownell's method.
* - Added some Seiko/Epson ID's. Thanks to Karl Heinz
* Kremer <khk@khk.net>.
* - Added some preliminary ioctl() calls for the PV8630 which is used
* by the HP4200. The ioctl()'s still have to be registered. Thanks
* to Adrian Perez Jorge <adrianpj@easynews.com>.
* - Moved/migrated stuff to scanner.h
* - Removed the usb_set_configuration() since this is handled by
* the usb_new_device() routine in usb.c.
* - Added the HP 3300C. Thanks to Bruce Tenison.
* - Changed user specified vendor/product id so that root hub doesn't
* get falsely attached to. Thanks to Greg K-H.
* - Added some Mustek ID's. Thanks to Gernot Hoyler
* <Dr.Hoyler@t-online.de>.
* - Modified the usb_string() reporting. See kfree() comment above.
* - Added Umax Astra 2000U. Thanks to Doug Alcorn <doug@lathi.net>.
* - Updated the printk()'s to use the info/warn/dbg macros.
* - Updated usb_bulk_msg() argument types to fix gcc warnings.
*
*
* 0.4 2/4/2000
*
* - Removed usb_string() from probe_scanner since the core now does a
* good job of reporting what was connnected.
* - Finally, simultaneous multiple device attachment!
* - Fixed some potential memory freeing issues should memory allocation
* fail in probe_scanner();
* - Some fixes to disconnect_scanner().
* - Added interrupt endpoint support.
* - Added Agfa SnapScan Touch. Thanks to Jan Van den Bergh
* <jan.vandenbergh@cs.kuleuven.ac.be>.
* - Added Umax 1220U ID's. Thanks to Maciek Klimkowski
* <mac@nexus.carleton.ca>.
* - Fixed bug in write_scanner(). The buffer was not being properly
* updated for writes larger than OBUF_SIZE. Thanks to Henrik
* Johansson <henrikjo@post.utfors.se> for identifying it.
* - Added Microtek X6 ID's. Thanks to Oliver Neukum
* <Oliver.Neukum@lrz.uni-muenchen.de>.
*
*
* 0.4.1 2/15/2000
*
* - Fixed 'count' bug in read_scanner(). Thanks to Henrik
* Johansson <henrikjo@post.utfors.se> for identifying it. Amazing
* it has worked this long.
* - Fixed '>=' bug in both read/write_scanner methods.
* - Cleaned up both read/write_scanner() methods so that they are
* a little more readable.
* - Added a lot of Microtek ID's. Thanks to Adrian Perez Jorge.
* - Adopted the __initcall().
* - Added #include <linux/init.h> to scanner.h for __initcall().
* - Added one liner in irq_scanner() to keep gcc from complaining
* about an unused variable (data) if debugging was disabled
* in scanner.c.
* - Increased the timeout parameter in read_scanner() to 120 Secs.
*
*
* 0.4.2 3/23/2000
*
* - Added Umax 1236U ID. Thanks to Philipp Baer <ph_baer@npw.net>.
* - Added Primax, ReadyScan, Visioneer, Colorado, and Genius ID's.
* Thanks to Adrian Perez Jorge <adrianpj@easynews.com>.
* - Fixed error number reported for non-existant devices. Thanks to
* Spyridon Papadimitriou <Spyridon_Papadimitriou@gs91.sp.cs.cmu.edu>.
* - Added Acer Prisascan 620U ID's. Thanks to Joao <joey@knoware.nl>.
* - Replaced __initcall() with module_init()/module_exit(). Updates
* from patch-2.3.48.
* - Replaced file_operations structure with new syntax. Updates
* from patch-2.3.49.
* - Changed #include "usb.h" to #include <linux/usb.h>
* - Added #define SCN_IOCTL to exclude development areas
* since 2.4.x is about to be released. This mainly affects the
* ioctl() stuff. See scanner.h for more details.
* - Changed the return value for signal_pending() from -ERESTARTSYS to
* -EINTR.
*
*
* 0.4.3 4/30/2000
*
* - Added Umax Astra 2200 ID. Thanks to Flynn Marquardt
* <flynn@isr.uni-stuttgart.de>.
* - Added iVina 1200U ID. Thanks to Dyson Lin <dyson@avision.com.tw>.
* - Added access time update for the device file courtesy of Paul
* Mackerras <paulus@samba.org>. This allows a user space daemon
* to turn the lamp off for a Umax 1220U scanner after a prescribed
* time.
* - Fixed HP S20 ID's. Thanks to Ruud Linders <rlinders@xs4all.nl>.
* - Added Acer ScanPrisa 620U ID. Thanks to Oliver
* Schwartz <Oliver.Schwartz@gmx.de> via sane-devel mail list.
* - Fixed bug in read_scanner for copy_to_user() function. The returned
* value should be 'partial' not 'this_read'.
* - Fixed bug in read_scanner. 'count' should be decremented
* by 'this_read' and not by 'partial'. This resulted in twice as many
* calls to read_scanner() for small amounts of data and possibly
* unexpected returns of '0'. Thanks to Karl Heinz
* Kremer <khk@khk.net> and Alain Knaff <Alain.Knaff@ltnb.lu>
* for discovering this.
* - Integrated Randy Dunlap's <randy.dunlap@intel.com> patch for a
* scanner lookup/ident table. Thanks Randy.
* - Documentation updates.
* - Added wait queues to read_scanner().
*
*
* 0.4.3.1

* Linders <rlinders@xs4all.nl>.
*
* 0.4.4
* - Added addtional Mustek ID's (BearPaw 1200, 600 CU, 1200 USB,
* and 1200 UB. Thanks to Henning Meier-Geinitz <henningmg@gmx.de>.
* - Added the Vuego Scan Brisa 340U ID's. Apparently this scanner is
* marketed by Acer Peripherals as a cheap 300 dpi model. Thanks to
* David Gundersen <gundersd@paradise.net.nz>.
* - Added the Epson Expression1600 ID's. Thanks to Karl Heinz
* Kremer <khk@khk.net>.
*
* 0.4.5 2/28/2001
* - Added Mustek ID's (BearPaw 2400, 1200 CU Plus, BearPaw 1200F).
* Thanks to Henning Meier-Geinitz <henningmg@gmx.de>.
* - Added read_timeout module parameter to override RD_NAK_TIMEOUT
* when read()'ing from devices.
* - Stalled pipes are now checked and cleared with
* usb_clear_halt() for the read_scanner() function. This should
* address the "funky result: -32" error messages.
* - Removed Microtek scanner ID's. Microtek scanners are now
* supported via the drivers/usb/microtek.c driver.
* - Added scanner specific read timeout's.
* - Return status errors are NEGATIVE!!! This should address the
* "funky result: -110" error messages.
* - Replaced USB_ST_TIMEOUT with ETIMEDOUT.
* - rd_nak was still defined in MODULE_PARM. It's been updated with
* read_timeout. Thanks to Mark W. Webb <markwebb@adelphia.net> for
* reporting this bug.
* - Added Epson Perfection 1640SU and 1640SU Photo. Thanks to
* Jean-Luc <f5ibh@db0bm.ampr.org> and Manuel

* - Print information about user-supplied ids only once at startup instead
* of every time any USB device is plugged in.
* - Removed PV8630 ioctls. Use the standard ioctls instead.
* - Made endpoint detection more generic. Basically, only one bulk-in
* endpoint is required, everything else is optional.
* - New maintainer: Henning Meier-Geinitz.
* - Print ids and device number when a device was detected.
* - Don't print errors when the device is busy.
*
* 0.4.11 2003-02-25

* Fujitsu, Hewlett-Packard, Lexmark, LG Electronics, Medion, Microtek,
* Primax, Prolink, Plustek, SYSCAN, Trust and UMAX scanners.
* - Fixed generation of devfs names if dynamic minors are disabled.
* - Used kobject reference counting to free the scn struct when the device
* is closed and disconnected. Avoids crashes when writing to a
* disconnected device. (Thanks to Greg KH).
*
* 0.4.12 2003-04-11
* - Fixed endpoint detection. The endpoints were numbered from 1 to n but
* that assumption is not correct in all cases.
*
* 0.4.13 2003-05-30
* - Added vendor/product ids for Genius, Hewlett-Packard, Microtek,
* Mustek, Pacific Image Electronics, Plustek, and Visioneer scanners.
* Fixed names of some other scanners.
*
* 0.4.14 2003-07-15

* - Added vendor/product ids for Avision, Canon, HP, Microtek and Relisys scanners.
* - Clean up irq urb when not enough memory is available.
*
* 0.4.15 2003-09-22
* - Use static declarations for usb_scanner_init/usb_scanner_exit
* (Daniele Bellucci).
* - Report back return codes of usb_register and usb_usbmit_urb instead of -1 or
* -ENONMEM (Daniele Bellucci).
* - Balancing usb_register_dev/usb_deregister_dev in probe_scanner when a fail
* condition occours (Daniele Bellucci).
* - Added vendor/product ids for Canon, HP, Microtek, Mustek, Siemens, UMAX, and
* Visioneer scanners.
* - Added test for USB_CLASS_CDC_DATA which is used by some fingerprint scanners.
*
* 0.4.16 2003-11-04
* - Added vendor/product ids for Epson, Genius, Microtek, Plustek, Reflecta, and
* Visioneer scanners. Removed ids for HP PSC devices as these are supported by
* the hpoj userspace driver.
*
* TODO
* - Performance
* - Select/poll methods
* - More testing
* - More general usage ioctl's
*
*
* Thanks to:
*
* - All the folks on the linux-usb list who put up with me. :) This
* has been a great learning experience for me.
* - To Linus Torvalds for this great OS.
* - The GNU folks.
* - The folks that forwarded Vendor:Product ID's to me.
* - Johannes Erdfelt for the loaning of a USB analyzer for tracking an
* issue with HP-4100 and uhci.
* - Adolfo Montero for his assistance.
* - All the folks who chimed in with reports and suggestions.
* - All the developers that are working on USB SANE backends or other
* applications to use USB scanners.
* - Thanks to Greg KH <greg@kroah.com> for setting up Brian Beattie
* and Henning Meier-Geinitz to be the new USB Scanner maintainer.
