I think you should be able to use any generic USB library
by linking to it from an Oct file and writing 
commands like:

1. open_oscilloscope()
2. set_parameter() #set voltage range, freq range, ac-dc etc
3. get_parameter() #get voltage, freq etc..
4. close_oscilloscope()

But Im not familiar with development using USB.
A simple search for development using the USB yields this
http://freshmeat.net/projects/libusb/
with functions present in it listed at
http://libusb.sourceforge.net/doc/functions.html
so that must help you get started, and with a little bit
of tweaking you must be on your way to use Octave with 
USB & Oscilloscope.
