A fair number of USB devices (keyboards in particular) use an
interface descriptor
other than the first available, making them non-functional currently.
To correct this, iterate through all available interface descriptors
until one with the correct class/subclass is found, then proceed to set the
configuration and setup the driver.
Tested on an ultimate hacking keyboard (UHK 60)

There are no longer any sleep or yield calls during the usb controller
device scans, so there is no need to run these device scans in a
separate thread.

Several users have reported devices that take more than 100ms to
announce their presence on a USB port. Allow the sigatt timeout to be
specified at runtime as a way to extend the default timeout.

The C code only uses _cfuncX_ prefixes for parameters to the call32(),
stack_hop_back(), and call32_params() functions. It's simpler to use
macro wrappers around those functions which provide the required
prefix.
This also changes the parameter order of stack_hop() and
stack_hop_back() to use the more natural (func, params) ordering.

This is the result of an audit of callers of the malloc_XXX() and
memalign_XXX() calls. All callers need to check if these functions
return NULL.

There is no need to pass 'cmdsize' to the usb drivers as the cmdsize

Now that all drivers have unified control and bulk transmit functions,
unify the driver calling code in usb.c as well.

Merge both the control and bulk pipe sending functions into one new
function: xhci_send_pipe(). This makes the xhci interface similar to
the other usb drivers.

Merge both the control and bulk pipe sending functions into one new
function: uhci_send_pipe(). The two existing functions were similar,
and by merging them the resulting code supports more flexible control

Support bulk transfers (usb drives) on OHCI USB controllers. Now that
there is support for 32bit only drive controllers, it is not that hard
to support disks on OHCI controllers, and it may be useful for some
old hardware.

Now that the usb controller drivers all support the realloc method,
use that for all pipe allocations, reallocations, and freeing. This
gives the driver more control over the pipe life cycle.

Instead of exporting both xhci_alloc_pipe() and xhci_update_pipe(),

Move the 100ms (USB_TIME_SIGATT) device detect polling from the
ohci/uhci/usb-hub code to the generic usb_hub_port_setup() code. This
extends the 100ms polling to ehci and xhci controllers. The code in
usb_hub_port_setup() now compares USB_TIME_SIGATT to the start of
usb_enumerate(), which may make boots faster when threads are
disabled.
This patch also changes the meaning of the return code for
hub->op->detect() calls. Now 1 indicates device found, 0 indicates
device not found, and -1 indicates permanent failure.
Also, the xhci controller generic delay of 100ms is replaced with a
20ms root hub power stabilize time. This in combination with the
100ms for USB_TIME_SIGATT should be closer to the USB2 spec (the USB3
spec does not seem to declare an equivalent of USB_TIME_SIGATT).

Make sure to wrap accesses to the usb_pipe struct with GET_LOWFLAT so
that it works in 16bit mode. This bug impacts both ehci and uhci usb
controllers (it should not impact ohci and xhci as those never call
the function in 16bit mode).

The xhci controller had a hardcoded 1 second timeout for both bulk and
control transfers. The 1 second bulk timeout is too small for some
real devices.
Increase both times to 5.1 seconds - according to the USB spec, the
maximum time a command should take is 5 seconds. However, have the
set_address command only wait for 150ms (spec says set_address should
take no more than 50ms).
Introduce usb_xfer_time() to calculate maximum command time.

Since the XHCI driver needs to jump into 32bit mode anyway, it is

It's easier to run the set_address from xhci_alloc_pipe as there is

The previous code attempts to correlate which UHCI and OHCI
controllers correlate with which EHCI controllers so that it can
ensure high speed devices are handled by the EHCI code while low/full
speed devices are handled by the UHCI/OHCI code. Replace this logic
by initializing all EHCI controllers first, and then initializing all
UHCI and OHCI controllers. This simplifies the code and improves
support for some hardware devices that don't follow the OHCI/UHCI to
EHCI correlation standard.
Also, remove the unused usb->busid field.

$subject says all. Support for usb3 streams is not implemented yet,
otherwise it is fully functional. Tested all usb devices supported
by qemu (keyboard, storage, usb hubs), except for usb attached scsi
in usb3 mode (which needs streams).
Tested on qemu only, tagged with QEMU_HARDWARE because of that.
Testing with physical hardware to be done.
