Recognized as aue not ugen, how do I do it?

[pbest at sdf.lonestar.org]

how would I configure my system such that a device supported by the aue
driver will load w/ it and not the generic ugen one?  aue and all
dependent driver are compiled into the system and loaded properly.  it
recognizes the name of the device "Siemens" but as ugen0.  Probably it
would include editing the parameters of usbd.conf? but how would I do that
such that it will work
