+config USB_STORAGE
+	tristate "USB Mass Storage support"
+	depends on SCSI
+	help
+	  Say Y here if you want to connect USB mass storage devices to your
+	  computer's USB port. This is the driver you need for USB
+	  floppy drives, USB hard disks, USB tape drives, USB CD-ROMs,
+	  USB flash devices, and memory sticks, along with
+	  similar devices. This driver may also be used for some cameras
+	  and card readers.
+
+	  This option depends on 'SCSI' support being enabled, but you
+	  probably also need 'SCSI device support: SCSI disk support'
+	  (BLK_DEV_SD) for most USB storage devices.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called usb-storage.
+

+	  this input in any keybinding software. (e.g. gnome's keyboard short-
+	  cuts)
+
+	  If this driver is compiled as a module, it will be named ums-onetouch.
+
+config USB_STORAGE_KARMA
+	tristate "Support for Rio Karma music player"
+	help
+	  Say Y here to include additional code to support the Rio Karma
+	  USB interface.
+
+	  This code places the Rio Karma into mass storage mode, enabling
+	  it to be mounted as an ordinary filesystem. Performing an eject
+	  on the resulting scsi device node returns the Karma to normal
+	  operation.
+
+	  If this driver is compiled as a module, it will be named ums-karma.
+
+config USB_STORAGE_CYPRESS_ATACB
+	tristate "SAT emulation on Cypress USB/ATA Bridge with ATACB"
+	help
+	  Say Y here if you want to use SAT (ata pass through) on devices based
+	  on the Cypress USB/ATA bridge supporting ATACB. This will allow you
+	  to use tools to tune and monitor your drive (like hdparm or smartctl).
+
+	  If you say no here your device will still work with the standard usb
+	  mass storage class.
+
+	  If this driver is compiled as a module, it will be named ums-cypress.
+
+config USB_STORAGE_ENE_UB6250
+	tristate "USB ENE card reader support"
+	help
+	  Say Y here if you wish to control a ENE SD/MS Card reader.
+	  Note that this driver does not support SM cards.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called ums-eneub6250.
+
+endif # USB_STORAGE
+
+config USB_UAS
+	tristate "USB Attached SCSI"
+	depends on SCSI && USB_STORAGE
+	help
+	  The USB Attached SCSI protocol is supported by some USB
+	  storage devices.  It permits higher performance by supporting
+	  multiple outstanding commands.
+
+	  If you don't know whether you have a UAS device, it is safe to
+	  say 'Y' or 'M' here and the kernel will use the right driver.
+
+	  If you compile this driver as a module, it will be named uas.

+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices.  Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document.  The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.

+ * Current development and maintenance:

+ *
+ * Developed with the assistance of:
+ *   (C) 2002 Alan Stern <stern@rowland.org>
+ *
+ * Initial work:
+ *   (C) 2000 In-System Design, Inc. (support@in-system.com)

+ * The ISD200 ASIC does not natively support ATA devices.  The chip
+ * does implement an interface, the ATA Command Block (ATACB) which provides
+ * a means of passing ATA commands and ATA register accesses to a device.
+ *
+ * History:
+ *
+ *  2002-10-19: Removed the specialized transfer routines.
+ *		(Alan Stern <stern@rowland.harvard.edu>)
+ *  2001-02-24: Removed lots of duplicate code and simplified the structure.
+ *	      (bjorn@haxx.se)
+ *  2002-01-16: Fixed endianness bug so it works on the ppc arch.
+ *	      (Luc Saillard <luc@saillard.org>)
+ *  2002-01-17: All bitfields removed.

+ * This driver is based on the 'USB Mass Storage Class' document. This

+ * mind when they created this document.  The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.

+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey

+ * Driver for USB Mass Storage compliant devices
+ * SCSI layer glue code
+ *
+ * Current development and maintenance by:
+ *   (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
+ *
+ * Developed with the assistance of:
+ *   (c) 2000 David L. Brown, Jr. (usb-storage@davidb.org)
+ *   (c) 2000 Stephen J. Gowdy (SGowdy@lbl.gov)
+ *
+ * Initial work by:
+ *   (c) 1999 Michael Gee (michael@linuxspecific.com)
+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices.  Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document.  The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.

+ * Many originally ATAPI devices were slightly modified to meet the USB
+ * market by using some kind of translation from ATAPI to USB on the host,
+ * and the peripheral would translate from USB back to ATAPI.
+ *
+ * SCM Microsystems (www.scmmicro.com) makes a device, sold to OEM's only, 
+ * which does the USB-to-ATAPI conversion.  By obtaining the data sheet on
+ * their device under nondisclosure agreement, I have been able to write
+ * this driver for Linux.
+ *
+ * The chip used in the device can also be used for EPP and ISA translation
+ * as well. This driver is only guaranteed to work with the ATAPI
+ * translation.
+ *
+ * See the Kconfig help text for a list of devices known to be supported by

+ * It is important to note that in a number of cases this class

+/*
+ * This is subtle, so pay attention:
+ * ---------------------------------
+ * We're very concerned about races with a command abort.  Hanging this code
+ * is a sure fire way to hang the kernel.  (Note that this discussion applies
+ * only to transactions resulting from a scsi queued-command, since only
+ * these transactions are subject to a scsi abort.  Other transactions, such
+ * as those occurring during device-specific initialization, must be handled
+ * by a separate code path.)
+ *
+ * The abort function (usb_storage_command_abort() in scsiglue.c) first
+ * sets the machine state and the ABORTING bit in us->dflags to prevent
+ * new URBs from being submitted.  It then calls usb_stor_stop_transport()
+ * below, which atomically tests-and-clears the URB_ACTIVE bit in us->dflags
+ * to see if the current_urb needs to be stopped.  Likewise, the SG_ACTIVE
+ * bit is tested to see if the current_sg scatter-gather request needs to be
+ * stopped.  The timeout callback routine does much the same thing.
+ *
+ * When a disconnect occurs, the DISCONNECTING bit in us->dflags is set to
+ * prevent new URBs from being submitted, and usb_stor_stop_transport() is
+ * called to stop any ongoing requests.
+ *
+ * The submit function first verifies that the submitting is allowed
+ * (neither ABORTING nor DISCONNECTING bits are set) and that the submit
+ * completes without errors, and only then sets the URB_ACTIVE bit.  This
+ * prevents the stop_transport() function from trying to cancel the URB
+ * while the submit call is underway.  Next, the submit function must test
+ * the flags to see if an abort or disconnect occurred during the submission
+ * or before the URB_ACTIVE bit was set.  If so, it's essential to cancel
+ * the URB if it hasn't been cancelled already (i.e., if the URB_ACTIVE bit
+ * is still set).  Either way, the function must then wait for the URB to
+ * finish.  Note that the URB can still be in progress even after a call to
+ * usb_unlink_urb() returns.
+ *
+ * The idea is that (1) once the ABORTING or DISCONNECTING bit is set,
+ * either the stop_transport() function or the submitting function
+ * is guaranteed to call usb_unlink_urb() for an active URB,
+ * and (2) test_and_clear_bit() prevents usb_unlink_urb() from being
+ * called more than once or from being called during usb_submit_urb().

+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class

+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey

+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.
