Hi,
I have an USB contactless reader which uses a FTDI chip. It works well with the
 current ftdi_sio driver, it's just a matter of adding an ID:

Thank you for sending this in.

Patch originally from Christian Groessler <cpg@aladdin.de> but cleaned up
by me.

Patch originally from Kevin Watkins <kw@cmu.edu>

We have found in the course of hacking on HAL that some information that
is in /proc/bus/usb/devices is not in sysfs.  It would be nice to rely
only on sysfs, so the attached patch adds three files to usb devices in
sysfs: devnum, maxChild, and version.

This patch is actually by David Zuethen, the HAL maintainer - I told him
I would clean it up and get it upstream.

Disable a usbfs disconnect() synchronization hack, which recently
started deadlocking because this routine is now called in a different
context.

It shouldn't be needed any longer now that usbcore shuts down endpoints
as part of driver unbinding.  (Except maybe on UHCI, which will have
canceled but not necessarily completed all requests.)

This helps Linux handle certain enumeration problems better,
by retrying most stalled descriptor fetches; on some devices,
those indicate temporary problems.  This match makes at least
one such (old) device enumerate reliably.

The per-port LEDs on the most USB 2.0 hubs are programmable.
And the USB spec describes some ways to use them, blinking
to alert users about hardware (amber) or software (green)
problems.

This patch is the infrastructure for that blinking.  And
if you should happen to "modprobe usbcore blinkenlights",
the LEDs will cycle through all the ports ... which is
not a USB-standard mode, but it can certainly handy be
handy as a system heartbeat visible across the room.

This fixes an oops during "ifconfig usb0 down" after unplug
from a Windows box.  It also shrinks the driver size to something
much more reasonable by leaving out debug messaging, and adds
a few missing newlines.

Generalize the driver a bit:

 - PCI-specific handling is restricted to a small chunk of
   init code.  Non-PCI implementations are in the pipeline.

 - Merge support from ARC International (Craig Nadler) for
   their integrated root hub transaction translators (on PCI).
   Other implementations should be similar.

Remove usb_interface.driver, and along with it the "half bound" state
previously associated with drivers binding with claim() instead of probe().
This changes usb_driver_claim_interface() semantics slightly: drivers must
now be prepared to accept disconnect() callbacks.

Fixes more locking bugs, and a claim() oops that snuck in with a
recent patch.

When David added an entry to the gadget_chips.h file for the dummy_hcd
driver, he mistakenly used the name "dummy_udc" rather than "dummy_hcd".
The mistake is understandable, since other controllers use "_udc" in their
names and it is illogical to put "_hcd" in a _device_ controller's name.

This patch updates the dummy_hcd driver and changes the gadget name to
agree with the gadget_chips.h entry.

This patch changes the UHCI driver's bus-release routine; now it will
correctly finish all pending but not-yet-completed URBs.  This fixes a
reported bug, when trying to rmmod uhci-hcd while using a USB mouse under
X.  Also, the patch changes a variable name from ...hs... to ...fs...
("high speed" -> "full speed") -- something I accidentally omitted in an
earlier patch.

This patch imports the endpoint auto-config library into the file-storage
gadget, simplifying the code needed for endpoint selection and removing
almost all dependencies on the controller type from the driver.  It also
changes some log messages for reporting fatal problems from INFO to ERROR.

This patch imports the config-buffer library into the file-storage gadget,
simplifying and decreasing the amount of code needed for assembling
configuration descriptors.  It also changes the driver to remove any
pretense at bus-powered operation and to use the new DUALSPEED
configuration option.  This is in line with recent changes made to other
gadget drivers.

This cleans up a larger amount of superfluos ";;" statements in current
Linux kernel sources by converting them to the regular single ";"
statments.

It seems to be a common problem that at the end of a line the semicolon
key is producing an echo.

The iSeries has an arch-specific mapping from physical <-> absolute
addresses.  Fortunately this is only used in a few places.  However, the
following arch-specific macros/functions are provided in addition to the
standard macros:

	__a2p()
	__a2v()
	__p2a()
	__p2v()
	__v2a()
	__v2p()
	absolute_to_phys()
	phys_to_absolute()
	virt_to_absolute()
	absolute_to_virt()

Reduce them to these, with slightly shorter names, and taking either pointers
or unsigned long (as per __va and __pa) rather than making the caller cast:

	abs_to_phys()
	phys_to_abs()

And helper macros:

	virt_to_abs()
	abs_to_virt()

As is standard, virtual addresses are returned as void *, physical and
absolute as unsigned long.

Note that the change the iSeries_setup is a little subtle: ea is set to
__va(pa) above, so "phys_to_abs(pa)" is the same as "virt_to_abs(ea)".

Also, REALADDR is renamed to ISERIES_HV_ADDR and used in a couple of places
where appropriate.

This patch just ensures that the RI bit is set really early as it seems it
is not on iSeries Power4 machines (or maybe OS400 v5r3 does this).

Well, when I did the grep that bug wasn't there; it
was just integrated on Feb 26!

The first part makes it use usb_reset_configuration() like
it did before ... I'm surprised this driver hasn't been
generating "it deadlocks during probe" reports.

The second part prints a diagnostic if the configuration
wasn't set right; the fix would use hotplug and sysfs.

This backs out Maneesh's sysfs patch that was recently added to the
kernel.

In its defense, the original patch did solve some fixes that could be
duplicated on SMP machines, but the side affect of the patch caused lots
of problems.  Basically it caused kobjects to get their references
incremented when files that are not present in the kobject are asked for
(udev can easily trigger this when it looks for files call "dev" in
directories that do not have that file).  This can cause easy oopses
when the VFS later ages out those old dentries and the kobject has its
reference finally released (usually after the module that the kobject
lived in was removed.)

I will continue to work with Maneesh to try to solve the original bug,
but for now, this patch needs to be applied.

The memory reserved for PCI probe is not freed properly in some cases,
for instance with a 3.5Gb of RAM.

Forward port from 2.4.

the attached patch should do the renaming everywhere hid or hid.o was
mentioned. It also removes all references to *.o module names.

Whoops, I missed something.  You should apply this patch too.

The RNDIS spec license agreement does NOT require tacking any
GPL-incompatible restrictions on the results of _using_ the
spec:

   "... may be used solely for the purpose of implementing
    the RNDIS protocol message set to interface with ..."
   (the two cases identified in the text)

And that's all the implementation does -- end of story.

This died a while ago, but lingers on in defconfigs.

datafab.c has an often-seen bug: the SCSI READ_CAPACITY command
does not need the number of sectors but the last sector.

I just tried the CF and SM parts of a 5-in-1 card reader.
The CF part works with US_PR_DATAFAB when the bug mentioned is fixed.
The SM part works with US_PR_SDDR55.
(Revision Number is 17.08 - that in case the 0000-ffff
should prove to be too optimistic.)

We still must discuss what setup to use for readers like this -
I have several of them - that require different drivers for
different LUNs. As it is now one has to compile usb-storage
twice, once with CONFIG_USB_STORAGE_DATAFAB defined and once
without, and remove one usb-storage.ko and insert the other
to go from CF to SM. (And that hangs with 2.6.4 so a reboot
is required..)

This patch fixes a bug in ftdi_sio.c where the driver wouldn't unlink the
read urb if the user application cleared the HUPCL flag on termios->c_cflag.
