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
properly.
This check was for back in the days when we only reported hotplug events
for the main usb device, not the interfaces. We should always give the
interface information for MODALIAS/modalias as it can be needed.

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
"version number" for these drivers.
This should also help reduce confusion when people try to ask for
support of a specific driver version, as there has been no way to tell
what they are talking about.

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.

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.

The PCI "early usb handoff" quirk logic didn't work like "ohci-hcd" ...
This patch makes it do so by:
- Resetting the controller after kicking BIOS off, matching the
normal "chip in hardware reset" startup mode;
- Reporting any BIOS that borks this simple handoff; it's likely
got a few other surprises for us too.
- Ignoring that handoff on HPPA;
The diagnostic string is mostly shared with EHCI, saving a few bytes.

This simplifies the OHCI root hub suspend logic:
- Uses new usbcore root hub calls to make autosuspend work again:
* Uses a newish usbcore root hub wakeup mechanism,
making requests to khubd not keventd.
* Uses an even newer sibling suspend hook.
- Expect someone always made usbcore call ohci_hub_suspend() before bus
glue fires; and that ohci_hub_resume() is only called after that bus
glue ran. Previously, only CONFIG_USB_SUSPEND promised those things.
(Includes updates to PCI and OMAP bus glue.)
- Handle a not-noticed-before special case during resume from one of
the swsusp snapshots when using "usb-handoff": the controller isn't
left in RESET state. (A bug to fix in the usb-handoff code...)
Also cleans up a minor debug printk glitch, and switches an mdelay over
to an msleep (how did that stick around for so long?).

This updates the PCI glue to address the new and simplified usbcore suspend
semantics, where CONFIG_USB_SUSPEND becomes irrelevant to HCDs because
hcd->hub_suspend() will always be called.
- Removes now-unneeded recursion support
- Go back to ignoring faults reported by the wakeup calls; we expect them
to fail sometimes, and that's just fine.
The PCI HCDs will need simple changes to catch up to this, like being able
to ignore the setting of CONFIG_USB_SUSPEND.

This patch associates hub suspend and resume logic (including for root hubs)
with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying
two troublesome versions of suspend logic into just one. It'll be easier to
keep things right from now on.
- Now usbcore _always_ calls hcd->hub_suspend as needed, instead of
only when USB_SUSPEND is enabled:
* Those root hub methods are now called from hub suspend/resume;
no more skipping between layers during device suspend/resume;
* It now handles cases allowed by sysfs or autosuspended root hubs,
by forcing the hub interface to resume too.
- All devices, including virtual root hubs, now get the same treatment
on their resume paths ... including re-activating all their interfaces.
Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and
updates the Kconfig to match the new definition of USB_SUSPEND: it provides
(a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream
from any device configuration which supports it.
This calls for minor followup patches for most HCDs (and their PCI glue).
