Large set of CAM improvements:
- Unify bus reset/probe sequence. Whenever bus attached at boot or later,
CAM will automatically reset and scan it. It allows to remove duplicate
code from many drivers.
- Any bus, attached before CAM completed it's boot-time initialization,
will equally join to the process, delaying boot if needed.
- New kern.cam.boot_delay loader tunable should help controllers that
are still unable to register their buses in time (such as slow USB/
PCCard/ CardBus devices), by adding one more event to wait on boot.
- To allow synchronization between different CAM levels, concept of
requests priorities was extended. Priorities now split between several
"run levels". Device can be freezed at specified level, allowing higher
priority requests to pass. For example, no payload requests allowed,
until PMP driver enable port. ATA XPT negotiate transfer parameters,
periph driver configure caching and so on.
- Frozen requests are no more counted by request allocation scheduler.
It fixes deadlocks, when frozen low priority payload requests occupying
slots, required by higher levels to manage theit execution.
- Two last changes were holding proper ATA reinitialization and error
recovery implementation. Now it is done: SATA controllers and Port
Multipliers now implement automatic hot-plug and should correctly
recover from timeouts and bus resets.
- Improve SCSI error recovery for devices on buses without automatic sense
reporting, such as ATAPI or USB. For example, it allows CAM to wait, while
CD drive loads disk, instead of immediately return error status.
- Decapitalize diagnostic messages and make them more readable and sensible.
- Teach PMP driver to limit maximum speed on fan-out ports.
- Make boot wait for PMP scan completes, and make rescan more reliable.
- Fix pass driver, to return CCB to user level in case of error.
- Increase number of retries in cd driver, as device may return several UAs.

changes was a semicolon cleanup from somebody else, this touches a lot more.
scratch_size was incorrectly passed as language ID when retrieving the language
ID table, this broke string retrieval on some devices.

Add a driver by Fredrik Lindberg for Option HSDPA USB devices. These differ
from standard 3G wireless units by supplying a raw IP/IPv6 endpoint rather than
using PPP over serial. uhsoctl(1) is used to initiate and close the WAN
connection.

Use the EVENTHANDLER system to hook into the usb device configuration and
perform a function such as ejecting a 3G autoinstaller disk. The eventhandler
system properly tracks threads and is safe to unload, remove the
setting/clearing of a function pointer in the kernel by u3g(4) which included a
tsleep for safety.
Add a quirk for the Curitel UM175 where setting multiplexing for call
management over the data endpoint causes communication to die.
Take this one step further and model it on the existing NetBSD quirk and import
other device IDs from them.

Fix hardware issue with FTDI chips: avoid sending a zero length packet due to
hardware sending garbage on ZLPs.

Remove overuse of exclamation marks in kernel printfs, there mere fact a
message has been printed is enough to get someones attention. Also remove the
line number for DPRINTF/DPRINTFN, it already prints the funtion name and a
unique message.
Disable interrupts after doing early takeover of the usb controller in case usb
isnt actually compiled in (or kldloaded) as the controller could cause spurious
interrupts.
Improve High Speed slot allocation mechanism by moving the computation to the
endpoint rather than per xfer and provide functions around get/free of resources.

ehci_init() will do reset and set the usbrev flag. Fix problem where
ehci_reset() was called before ehci_init().

- Add usb_fill_bulk_urb() and usb_bulk_msg() linux compat functions [1]
- Don't write actual length if the actual length pointer is NULL [2]
- correct Linux Compatibility error codes for short isochronous IN transfers
and make status field signed.

updates device entries supported with the product name not magic numbers
and sorts entries. WUSB54GCV2 is added.
overhauls urtw(4) for supporting RTL8187B devices properly that there
was major changes to initialize RF chipset and set H/W registers and
removed a lot of magic numbers on code.
Reduce probe priority of USB input devices to BUS_PROBE_GENERIC from
BUS_PROBE_SPECIFIC. This allows device-specific drivers like atp to
attach reliably.
Integrate lost interrupts patch from the old USB stack.
Some EHCI chips from VIA / ATI seem to trigger interrupts before writing back
the qTD status, or miss signalling occasionally under heavy load. If the host
machine is too fast, we can miss transaction completion - when we scan the
active list the transaction still seems to be active. This generally exhibits
itself as a umass stall that never recovers.
We work around this behaviour by setting up this callback after any softintr
that completes with transactions still pending, giving us another chance to
check for completion after the writeback has taken place
