/* This needs more work before we can enable it.  Unfortunately
 * because of the fancy asynchronous way URB status/error is written
 * back to userspace, we'll need to fiddle with USB devio internals
 * and/or reimplement entirely the frontend of it ourselves. -DaveM
 *
 * The issue is:
 *
 *	When an URB is submitted via usbdevicefs it is put onto an
 *	asynchronous queue.  When the URB completes, it may be reaped
 *	via another ioctl.  During this reaping the status is written
 *	back to userspace along with the length of the transfer.
 *
 *	We must translate into 64-bit kernel types so we pass in a kernel
 *	space copy of the usbdevfs_urb structure.  This would mean that we
 *	must do something to deal with the async entry reaping.  First we
 *	have to deal somehow with this transitory memory we've allocated.
 *	This is problematic since there are many call sites from which the
 *	async entries can be destroyed (and thus when we'd need to free up
 *	this kernel memory).  One of which is the close() op of usbdevicefs.
 *	To handle that we'd need to make our own file_operations struct which
 *	overrides usbdevicefs's release op with our own which runs usbdevicefs's
 *	real release op then frees up the kernel memory.
 *
 *	But how to keep track of these kernel buffers?  We'd need to either
 *	keep track of them in some table _or_ know about usbdevicefs internals
 *	(ie. the exact layout of it's file private, which is actually defined
 *	in linux/usbdevice_fs.h, the layout of the async queues are private to
 *	devio.c)
 *
 * There is one possible other solution I considered, also involving knowledge
 * of usbdevicefs internals:
 *
 *	After an URB is submitted, we "fix up" the address back to the user
 *	space one.  This would work if the status/length fields written back
 *	by the async URB completion lines up perfectly in the 32-bit type with
 *	the 64-bit kernel type.  Unfortunately, it does not because the iso
 *	frame descriptors, at the end of the struct, can be written back.
 *
 * I think we'll just need to simply duplicate the devio URB engine here.
