in SUPER-speed mode, USB 3.0.
This feature has not been tested yet, due to lack of hardware.
This feature is useful when implementing protocols like UASP,
USB attached SCSI which promises higher USB mass storage throughput.
This patch also implements support for hardware processing of endpoints
for increased performance. The switching to hardware processing
of an endpoint is done via a callback to the USB controller driver. The
stream feature is implemented like a variant of a hardware USB protocol.
USB controller drivers implementing device mode needs to be updated to
implement the new "xfer_stall" USB controller method and remove the
"xfer" argument from the "set_stall" method.
The API's toward existing USB drivers are preserved. To setup a USB transfer
in stream mode, set the "stream_id" field of the USB config structure to
the desired value.
The maximum number of BULK streams is currently hardcoded and limited to 8
via a define in usb_freebsd.h.
All USB drivers should be re-compiled after this change.
LibUSB will be updated next week to support streams mode. A new IOCTL to
setup BULK streams as already been implemented. The ugen device nodes
currently only supports stream ID zero.
The FreeBSD version has been bumped.

Also, remove usb_malloc_type: it was unused.
Remove METHODS_NONE: it was unused.
Move include of opt_usb.h from usb_port.h to usb.h, since usb_port.h is
going away (there will be a usb_compat.h for out-of-tree drivers that want it).

lack a report descriptor and don't use the standard interface class.
This patch works around these deficiencies so that the uhid(4) driver
can recognize and use those broken devices.

Split the attach/detach events up into device, driver and controller
attach and detach events.
The commit message from NetBSD was:
date: 2000/02/02 07:34:00; author: augustss; state: Exp;
Change the USB event mechanism to include more information
about devices and drivers. Partly from FreeBSD.
Also rework usbd to take these new event types into account.
date: 2000/02/29 21:37:01; author: augustss; state: Exp;
Distinguish between device and interface classes.
(I finally found a document that said that they were different.)
Make it possible to move a device to its unconfigured state by
using config #0.
Add some comments.
Change error reporting in port reset function.
usbd_devinfo_vp(): search the know devs array also if the device doesn't
return product description (e.g. Kye's Genius NetScroll mouse returns
vendor, but not product); the strings returned by device are still
preferred to those in the array, though
and has not been loaded via a kldload,
running usbd(8) will autoload the "usb.ko" kld.
thanks to Peter Wemm for enlightening me on the
differences between kldfind(2) and modfind(2).
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.
