The EHCI_CAPLENGTH and EHCI_HCIVERSION registers are actually sub-registers within the first 4 bytes of the EHCI memory space. For controllers that use big-endian MMIO, reading them with 1- and 2-byte reads would then return the wrong values. Instead, read the combined register with a 4-byte read and mask out the interesting quantities.

The problem was that the EHCI driver was then thinking that the transfer was immediately complete in some cases.

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

EHCI Hardware BUG workaround
The EHCI HW can use the qtd_next field instead of qtd_altnext when a short packet is received. This contradicts what is stated in the EHCI datasheet. Also the total-bytes field in the status field of the following TD gets corrupted upon reception of a short packet! We work this around in software by not queueing more than one job/TD at a time of up to 16Kbytes! The bug has been seen on multiple INTEL based EHCI chips. Other vendors have not been tested yet.
- Applications using /dev/usb/X.Y.Z, where Z is non-zero are affected, but not applications using LibUSB v0.1, v1.2 and v2.0. - Mass Storage (umass) is affected.

This change is about removing three fields from "struct usb2_xfer" which can be reached from "struct usb2_xfer_root" instead and cleaning up the code after this change. The fields are "xfer->udev", "xfer->xfer_mtx" and "xfer->usb2_sc". In this process the following changes were also made: Rename "usb2_root" to "xroot" which is short for "xfer root". Rename "priv_mtx" to "xfer_mtx" in USB core. The USB_XFER_LOCK and USB_XFER_UNLOCK macros should only be used in the USB core due to dependency towards "xroot". Substitute macros for the real lock in two USB device drivers.

Convert the two main locking areas into macros to make it clear on what we are grabbing and why. These are now:
USB_BUS_LOCK/USB_BUS_UNLOCK USB_XFER_LOCK/USB_XFER_UNLOCK

Bring in USB4BSD, Hans Petter Selasky rework of the USB stack that includes significant features and SMP safety.
This commit includes a more or less complete rewrite of the *BSD USB stack, including Host Controller and Device Controller drivers and updating all existing USB drivers to use the new USB API:
1) A brief feature list:
- A new and mutex enabled USB API.
- Many USB drivers are now running Giant free.
- Linux USB kernel compatibility layer.
- New UGEN backend and libusb library, finally solves the "driver unloading" problem. The new BSD licensed libusb20 library is fully compatible with libusb-0.1.12 from sourceforge.
- New "usbconfig" utility, for easy configuration of USB.
- Full support for Split transactions, which means you can use your full speed USB audio device on a high speed USB HUB.
- Full support for HS ISOC transactions, which makes writing drivers for various HS webcams possible, for example.
- Full support for USB on embedded platforms, mostly cache flushing and buffer invalidating stuff.
- Safer parsing of USB descriptors.
- Autodetect of annoying USB install disks.
- Support for USB device side mode, also called USB gadget mode, using the same API like the USB host side. In other words the new USB stack is symmetric with regard to host and device side.
- Support for USB transfers like I/O vectors, means more throughput and less interrupts.
- ... see the FreeBSD quarterly status reports under "USB project"
2) To enable the driver in the default kernel build:
2.a) Remove all existing USB device options from your kernel config file.
2.b) Add the following USB device options to your kernel configuration file:
# USB core support device usb2_core
# USB controller support device usb2_controller device usb2_controller_ehci device usb2_controller_ohci device usb2_controller_uhci
# USB mass storage support device usb2_storage device usb2_storage_mass
# USB ethernet support, requires miibus device usb2_ethernet device usb2_ethernet_aue device usb2_ethernet_axe device usb2_ethernet_cdce device usb2_ethernet_cue device usb2_ethernet_kue device usb2_ethernet_rue device usb2_ethernet_dav
# USB wireless LAN support device usb2_wlan device usb2_wlan_rum device usb2_wlan_ral device usb2_wlan_zyd
# USB serial device support device usb2_serial device usb2_serial_ark device usb2_serial_bsa device usb2_serial_bser device usb2_serial_chcom device usb2_serial_cycom device usb2_serial_foma device usb2_serial_ftdi device usb2_serial_gensa device usb2_serial_ipaq device usb2_serial_lpt device usb2_serial_mct device usb2_serial_modem device usb2_serial_moscom device usb2_serial_plcom device usb2_serial_visor device usb2_serial_vscom
# USB bluetooth support device usb2_bluetooth device usb2_bluetooth_ng
# USB input device support device usb2_input device usb2_input_hid device usb2_input_kbd device usb2_input_ms
# USB sound and MIDI device support device usb2_sound
2) To enable the driver at runtime:
2.a) Unload all existing USB modules. If USB is compiled into the kernel then you might have to build a new kernel.
2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same base name like the kernel device option.
