This patch from Alan Stern started as as568. It has been rediffed against
a current tree.
This patch adds minimal suspend/resume support to usb-storage. Just enough
for it to qualify as PM-aware.

This patch is from Alan Stern (as560). It has been rediffed against a
current tree.
This patch allocates a separate buffer for usb-storage to use when
auto-sensing. Up to now we have been using the sense buffer embedded in a
scsi_cmnd struct, which is dangerous on hosts that (a) don't do
cache-coherent DMA or (b) have DMA alignment restrictions.

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.

Vojtech says it's worth trying, since it might help with some recalcitrant

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.

Looks okay to me. Given that the previous entry uses the full 0000 -
9999 range, I guess this one can also. The vendor name is a little odd
(it will give us three different vendor names all in entries with the
same vendor ID) but that doesn't really matter either.

This fixes a problem with some cdc acm devices that were not getting
automatically loaded as the module alias was not being reported

This check was for back in the days when we only reported hotplug events

These numbers are pointless, as they have not been changed in _years_,
so we should just remove them to stop pretending there is an actual

When a USB device is put into suspend mode, the current drawn from VBUS
has to be less than 500 uA. Some transceivers need to be put into a
special power-saving mode to accomplish this, and won't have a separate
OTG driver handling that.
This adds a suspend method to the "otg_transceiver" struct -- misnamed,
it's not only for OTG -- and calls it from the OMAP UDC driver.

The change to make DMA work two bytes at a time omitted an important
tweak that affects the file_storage gadget: it needs to recognize when
the host writes an odd number of bytes. (The network layer ignores
such extra bytes.)
This patch resolves that issue by checking the relevant bit and adjusting
the rx byte count, so that for example a legal 13 byte request doesn't
morph into an illegal 14 byte one any more.

The uhci-hcd driver is fairly lax about the way it handles isochronous
transfers. This patch (as579) improves it in three respects:
TDs for a new URB aren't added to the schedule until all of
them have been allocated. This way there's no risk of the
controller executing some of them when an allocation fails.
TDs for an unlinked URB are removed from the schedule as soon
as the URB is unlinked, rather than waiting until the URB is
given back. This way there's no risk of the controller still
executing a TD after the URB completes.
The urb->error_count values are now reported correctly.
Although since they aren't used in any drivers except for
debug messages in the system log, probably nobody cares.

This patch (as580) is perhaps the only result from the long discussion I
had with David about his changes to the root-hub suspend/resume code. It
renames the hub_suspend and hub_resume methods in struct usb_hcd to
bus_suspend and bus_resume. These are more descriptive names, since the
methods really do suspend or resume an entire USB bus, and less likely to
be confused with the hub_suspend and hub_resume routines in hub.c.
It also takes David's advice about removing the layer of bus glue, where
those methods are called. And it implements a related change that David
made to the other HCDs but forgot to put into dummy_hcd.

This patch (as574) updates the PCI BIOS usb-handoff code for UHCI
controllers, making it work like the reset routines in uhci-hcd. This
allows uhci-hcd to drop its own routines in favor of the new ones
(code-sharing).
Once the patch is merged we can turn the usb-handoff option on
permanently, as far as UHCI is concerned. OHCI and EHCI may still have
some issues.

There appears to be one more case where the HP8200 CD writer devices are
detected as flash readers - when the USB cable is replugged after use, with
the power cable still connected.
Oddly enough, the identify device command appears to 'fall through' when the
devices are in this state, the status register reading exactly the same opcode
as the command (0xA1) that was just executed.
I think it's safe to label this behaviour as specific to HP8200 devices, I
can't get the flash devices to respond like this.
This patch should solve the last of the HP8200 issues which have cropped up
recently.

Because there is no bulk_interrupt_message() routine and no
USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the
usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt
transfers as well as bulk transfers.
This patch (as567) formalizes this practice and adds code to
usb_bulk_message() for detecting when the target is really an interrupt
endpoint. If it is, the routine submits an interrupt URB (using the
default interval) instead of a bulk URB. In theory this should help HCDs
that don't like it when people try to mix transfer types, queuing both
periodic and non-periodic types for the same endpoint.
Not fully tested -- I don't have any programs that use USBDEVFS_BULK for
interrupt transfers -- but it compiles okay and normal bulk messages work
as well as before.
