This patch (as1111) fixes a bug in the hub driver. When a hub
resumes, disconnections that occurred while the hub was suspended are
lost.
A completely different fix for this problem has already been accepted
for 2.6.27; however the problem still needs to be handled in 2.6.26.

USB: fix interrupt disabling for HCDs with shared interrupt handlers
As has been discussed several times on LKML, IRQF_SHARED | IRQF_DISABLED
doesn't work reliably, i.e. a shared interrupt handler CAN'T be certain to
be called with interrupts disabled. Most USB HCD handlers use IRQF_DISABLED
and therefore havoc can break out if they share their interrupt with a
handler that doesn't use it.
On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED)
was registered before ehci_hcd and one uhci_hcd instance. Therefore all
usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance
happened with interrupts enabled. That led to random lockups as USB core
HCD functions that acquire the same spinlock could be called twice
from interrupt handlers.
This patch updates usb_hcd_irq() to always disable/restore interrupts.
usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.

Here's a new device ID for the ftdio_sio driver.
The diff is with linus's tree as of this morning.
The device is the RigExpert Tiny USB Soundcard Transceiver Interface for ham
radio.
(I didn't actually test this. A fellow ham couldn't get the device to work, and
I suggested binding the device ID using sysfs - see
"http://jk.ufisa.uninett.no/usb/". However, he had had moved on to other things
by then. I guess adding the device ID to the kernel "on spec" won't hurt.

This patch fixes a problem with OHCI where canceling bulk or
interrupt URBs may lose track of the right data toggle. This
seems to be a longstanding bug, possibly dating back to the
Linux 2.4 kernel, which stayed hidden because
(a) about half the time the data toggle bit was correct;
(b) canceling such URBs is unusual; and
(c) the few drivers which cancel these URBs either
[1] do it only as part of shutting down, or
[2] have fault recovery logic, which recovers.
For those transfer types, the toggle is normally written back
into the ED when each TD is retired. But canceling bypasses
the mechanism used to retire TDs ... so on average, half the
time the toggle bit will be invalid after cancelation.
The fix is simple: the toggle state of any canceled TDs are
propagated back to the ED in the finish_unlinks function.

This patch fixes a regression in the EHCI driver's TIMER_IO_WATCHDOG
behavior. The patch "USB: EHCI: add separate IAA watchdog timer" changed
how that timer is handled, so that short timeouts on the remaining
timer (unfortunately, overloaded) would never be used.
This takes a more direct approach, reorganizing the code slightly to
be explicit about only the I/O watchdog role now being overridable.
It also replaces a now-obsolete comment describing older timer behavior.

This patch tries to identify which devices are able to accept
reset-resume handling, by checking that there is at least one
interface driver bound and that all of the drivers have a reset_resume
method defined. If these conditions don't hold then during resume
processing, the device is logicall disconnected.
This is only a temporary fix. Later on we will explicitly unbind
drivers that can't handle reset-resumes.

This patch (as1099) fixes a performance regression in ehci-hcd. The
fundamental problem is that queue headers get removed from the
schedule too quickly, since the code checks for a counter advancing
rather than making an actual time-based check. The latency involved
in removing the queue header and then relinking it can severely
degrade certain kinds of workloads.
The patch replaces a simple counter with a timestamp derived from the
controller's uframe value. In addition, the delay for unlinking an
idle queue header is increased from 5 ms to 10 ms; since some
controllers (nVidia) have a latency of up to 1 ms for unlinking, this
reduces the relative impact from 20% to 10%.
Finally, a logical error left over from the IAA watchdog-timer
conversion is corrected. Now the driver will always either unlink an
idle queue header or set up a timer to unlink it later. The old code
would sometimes fail to do either.

This patch (as1098) changes the way ehci-hcd schedules its periodic
Iso transfers. That the current scheduling code is wrong is clear on
the face of it: Sometimes it returns -EL2NSYNC (meaning that an URB
couldn't be scheduled because it was submitted too late), but it does
this even when the URB_ISO_ASAP flag is set (meaning the URB should be
scheduled as soon as possible).
The new code properly implements as-soon-as-possible scheduling,
assigning the next unexpired slot as the URB's starting point. It
also is more careful about checking for Iso URB completion: It doesn't
bother to check for activity during frames that are already over,
and it allows for the possibility that some of the URB's packets may
have raced the hardware when they were submitted and so never got used
(the packet status is set to -EXDEV).
This fixes problems several people have experienced with USB video
applications.

enumerate at high speed and then is handed over to the companion
controller. But usbcore logs a misleading and unwanted error message

a port has been handed over to a companion controller. If it has, the
error message is suppressed.

This patch (as1095) cleans up the HCD glue and several of the EHCI
bus-glue files. The ehci->is_tdi_rh_tt flag is redundant, since it
means the same thing as the hcd->has_tt flag, so it is removed and the
other flag used in its place.
Some of the bus-glue files didn't get the relinquish_port method added
to their hc_driver structures. Although that routine currently
doesn't do anything for controllers with an integrated TT, in the
future it might. So the patch adds it where it is missing.
Lastly, some of the bus-glue files have erroneous entries for their
hc_driver's suspend and resume methods. These method pointers are
specific to PCI and shouldn't be used otherwise.
(The patch also includes an invisible whitespace fix.)

This patch (as1094) changes the output of the "descriptors" binary
attribute. Now it will contain the device descriptor followed by all
the configuration descriptors, not just the descriptor for the current
config.
Userspace libraries want to have access to the kernel's cached
descriptor information, so they can learn about device characteristics
without having to wake up suspended devices. So far the only user of
this attribute is the new libusb-1.0 library; thus changing its
contents shouldn't cause any problems.
This should be considered for 2.6.26, if for no other reason than to
minimize the range of releases in which the attribute contains only the
current config descriptor.
Also, it doesn't hurt that the patch removes the device locking --
which was formerly needed in order to know for certain which config was
indeed current.

There is a potential deadlock when the usb_generic driver is unbound
from a device. The problem is that generic_disconnect() is called
with the device lock held, and it removes a bunch of device attributes
from sysfs. If a user task happens to be running an attribute method
at the time, the removal will block until the method returns. But at
least one of the attribute methods (the store routine for power/level)
needs to acquire the device lock!
This patch (as1093) eliminates the deadlock by moving the calls to
create and remove the sysfs attributes from the usb_generic driver
into usb_new_device() and usb_disconnect(), where they can be invoked
without holding the device lock.
Besides, the other sysfs attributes are created when the device is
registered and removed when the device is unregistered. So it seems
only fitting for the extra attributes to be created and removed at the
same time.

Uninitialised Apple iSight drivers present with a distinctive USB ID.
Once firmware has been uploaded, they disconnect and reconnect with a
new ID. At this point they can be driven by the uvcvideo driver. As this
is unique to the Apple cameras and not functionality shared by any other
UVC devices, it makes sense to provide the firmware loading
functionality in a separate driver. This driver will read an isight.fw
file extracted from the Apple driver using the tools at
http://bersace03.free.fr/ift/ and upload it to the camera. It will also
handle the case where the device loses its firmware during hibernation
and must have it reloaded.

This adds the Telit UC864-E HDSPA modem support to the option driver.
This lets their customers comply with the GPL instead of having to use a
binary driver from the manufacturer.

There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.
This patch fixes the problem by using the new function,
device_create_drvdata().

This patch fixes the problem by using the new function,
device_create_drvdata(). It fixes all 3 phidget drivers, which all have
the same problem.
