In a separate but related change, when a usb_reset_configuration call
fails, the device state is not changed to USB_STATE_ADDRESS.  In the
first place, failure means that we don't know what the state is, not
that we know the device is unconfigured.  In the second place, doing

realize there still is a current configuration that needs to be
destroyed.

[PATCH] usbcore: Improve endpoint sysfs file handling

This revised patch (as587b) improves the implementation of USB endpoint
sysfs files.  Instead of storing a whole bunch of attributes for every

share a static list of attributes.  The number of extra fields added to

The bEndpointAddress field is retained even though it is redundant (it
repeats the same information as the attributes' directory name).  The
code avoids calling kobject_register, to prevent generating unwanted

[PATCH] PATCH: usb-storage: move GetMaxLUN later in time

This patch is originally from Alan Stern (as557).  It has been re-diffed
against a current tree, and I also corrected a minor merging error.

Some time ago we introduced a delay before device scanning, because many
devices do not like to receive SCSI commands right after enumeration.
Now it turns out there's a device that doesn't like to receive
Get-Max-LUN right after enumeration either.  Accordingly this patch
delays the Get-Max-LUN request until the beginning of the scanning
procedure.  This fixes Bugzilla entry #5010.

Three things are worth noting.  First, I removed the locking code from
usb_stor_acquire_resources.  It's not needed, because the locking is to
protect against disconnect events and acquire_resources is only called
during probe (so the disconnect routine can't be called).  Second, I
initialized to 0 the buffer used for the Get-Max-LUN response.  It's not
really necessary, but it will prevent random values from showing up in
the debugging log when the request fails.  Third, I added a test against
the SINGLE_LUN flag.  This will allow us to use the flag to indicate
Bulk-only devices that can't handle Get-Max-LUN.

[PATCH] hid-core: Add Clear-Halt on the Interrupt-in endpoint

This patch (as577) adds a Clear-Halt call on the Interrupt-in endpoint
during input device configuration.  Without it my HP USB keyboard doesn't
work.

Vojtech says it's worth trying, since it might help with some recalcitrant
devices.  On the other hand, it might interfere with others.  I'm
submitting it so that it can get tested by a range of users.

[PATCH] USB: Always do usb-handoff

This revised patch (as586b) makes usb-handoff permanently true and no
longer a kernel boot parameter.  It also removes the piix3_usb quirk code;
that was nothing more than an early version of the USB handoff code
(written at a time when Intel's PIIX3 was about the only motherboard with
USB support).  And it adds identifiers for the three PCI USB controller
classes to pci_ids.h.
