Change (almost) all static to Static. The symbol `Static' can then be defined
...
to `' or `static' depending on if you want to debug or not.

Add an argument to usbd_open_pipe_intr() to specify the polling interval

Turn xfer allocation into a method in the HC driver. The reason is that

an HC driver may want to subclass the xfer to have additional private fields.

Add usbd_reload_device_desc() to get the device descriptor again from a device.

XXX Add a temporary, gruesome hack. It allows transfers to
...
XXX be done using delay() instead of tsleep().
XXX This enables transfers to be made from an interrupt context, which
XXX is needed until some more threads are added to the kernel.
XXX Using this hack (which is rare) causes the kernel to busy-wait
XXX for up to 1 ms at splusb().

* Move DMA buffer allocation to HC independent code.

* Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

Change the internal API to allow DMA buffers to be pre-allocated by
...
the device driver instead of happening automagically in the HC driver.
This affects both the HC-USBD interface as well as the USBD-device
interface.
This change will allow DMA buffers to be reused e.g. in isochronous
traffic.
Add isochronous support to the UHCI driver (not for OHCI yet).

Make sure to mark the device as dying already in the (de)activate routine.

This avoids access to it before the detach routine has blown it away.

Get rid of a bunch of code that was part of an old USBDI proposal, but that
...
is unused in our USB stack.
Once upon a time, when I started writing the USB stack for NetBSD, there
was an effort to make a standard for how USB device drivers should interact
with the rest of the USB stack. This effort had contributors from just
about all Un*x camps (but not Micro$oft :). I based my design on one of their
early proposals since I thought it would be a good idea if we could all
share device drivers with a minimum effort. Shortly after I started my work
all the free Un*x people were thrown out of the USBDI work since we did not
pay the USB membership fee. Well, some time has passed now and the work of
the standardization group is almost public again. But alas, the new standard
has grown to be a monster! I do not want to have this as the basis for the
*BSD USB stack; it is far too complicated.
So, since we are not even close to being compilant with the standard, I've
thrown out some old baggage.
