I have a Linux application that talks to an USB audio dongle that I'm trying to 
port to FreeBSD.  I have no problem with the audio portion, but I'm also trying 
to use libusb to access the GPIO bits on the chip.  If I don't load snd_uaudio 
/dev/ugen shows up and libusb works fine and I can access the GPIO.  However 
when the sound driver is loaded ugen doesn't bind to the device so libusb can't 
talk to it.  I need simultaneous access to the GPIO and audio functions, either 
or isn't acceptable.  The GPIO bits I need are not supported by HID so that's 
not an option.

Can anyone suggest a solution? 

Thanks!
