Many usb devices can be attached as different devices along with 
being functional with some libusb app that requires ugen.
eg.  HP PSC Printers will attach as ulpt, if ulpt isn't loaded umass 
can attach to access the card slot, if neither of these are loaded 
ugen will attach which is required to run the hplip vendor software 
so that the printer, scanner, and fax machine can be accessed.
        It would be very helpful to allow ulpt, umass, and ugen to all attach 
to the device.  This would allow full functionality.  Simultaneous 
access isn't necessary, but might be nice in the future.
        I believe I mentioned this before, but I'd like to actually implement 
this now.  At least allow ugen to attach to all devices along side 
the native driver.  I'd to do this on the HPS stack and then maybe 
port the changes to 6.x.
        The closest thing I can think of that allows similar behavior is 
vgapci that allow acpi_video and a drm driver to both access the 
video card.

Any pointers should be appreciated.

Thanks,
