f1129b105e Provide the USB device release number along with other parameters
so that devd can match on it. This field was already available to
usbd and is used by a number of usbd.conf entries, so now it is
possible to transfer those entries to devd.conf.

3ecc7feefc Take out Giant in uhub_child_* in giant. There's one place where we
could sleep which I think can lead to races.  However, there are fewer
with this code than without it.

e2b66de827 Use usbd_get_string() instead of calling usbd_get_string_desc()
with the wrong language parameter when retrieving the device serial
number. This invalid request caused some devices not to work at
all.

f79bef6097 Merge recent USB2/EHCI related changes from NetBSD:
o Reduce the interrupt delay to 2 microframes.
 o Follow the spec more closely when updating the overlay qTD in the QH.
 o No need to generate an interrupt at the data part of a control
   transfer, it's generated by the status transfer.
 o Make sure to update the data toggle on short transfers.
 o Turn the printf about needing toggle update into a DPRINTF.
 o Keep track of what high speed port (if any) a device belongs to
   so we can set the transaction translator fields for the transfer.
 o Verbosely refuse to open low/full speed pipes that depend on
   unimplemented split transaction support.
 o Fix various typos in comments.

9c56382454 We don't need a uhub_child_detached() routine now that we don't detach
device_t instances when no driver attaches.  They are left around, and
we need to remember them.

# The usbd_device_handle->subdevs[] array likely is completely bogus
# at this point, but one change at a time, since its removal will need
# to have similar code replace it extracted from newbus.

Part of the patch submitted by Peter Pentchev after an excellent
analysis of the underlying problems.

487d427700 Next step in making usb more newbus:
o reprobe children when a new driver is added to uhub
o fix the usbd_probe_and_attach to set the ivars to a malloc'd area, as well
  as freeing the ivars on child destruction.
o Don't delete children that don't attach. Evidentally, the need to do this
  is a common misconception.
o minor formatting foo that may violate style(9) at the moment, but keeps the
  diffs against my p4 tree smaller.

This does not solve the ugen gobbling things up problem, but the fixes
I have for that expose bugs in other parts of the tree...

f2b2cfdac0 Initialise `restartcnt' in the newly malloc'd usbd_port structure,
as otherwise the junk it contains may cause uhub_explore to give
up without ever trying to restart the port. This fixes the following
errors I was seeing with a VIA UHCI controller:

	uhub0: port error, restarting port 1
	uhub0: port error, giving up port 1

753bb32e49 As defined by USB Specification Rev 2.0 (in section 11.24.2.5), to
get a Hub descriptor, we have to set req.wValue to "Descriptor Type
and Descriptor Index". In this case, Descriptor Type is 0x29
(UDESC_HUB), Descriptor Index should be 0.

If I don't do a check (dev->address > 1 ... ), root hub fails.

A new Cytronix 4-port USB 2.0 Hub (Cypress CY7C65640 chip) now works
after this patch.

d8880ad0bd Avoid reprobing on loading a driver. This does not work as the ivars set
during the previous probe are stale.

What really should be done is route the probe through
device_probe_and_attach bit this is one of those ICBBATIASS (I can't be
bothered as there is a simpler solution). The user can easily replug the
device after kldloading a new device driver.

    Change the operation of the USB event thread.  Before it only
    performed USB device discovery, now it can also perform (short)
    tasks for device drivers that need a process context, but don't
    have one.  This is not pretty, but better than using busy-wait
    in an interrupt context.
