Thanks John for answering.

I do not have a USB-ethernet device here to test. I have found a 
USB/Wireless card (official RaspberryPi). I have just plugged it in. Now 
there are two devices bwfm0 and bwfm1  even I only setup one of them in 
rc.conf:

#ifconfig_bwfm0="up"
ifconfig_bwfm1="up"

I had manually

ifconfig bwfm0 down

to disable the internal wireless card.

raspa-netbsd# ifconfig

Althoug it is the same driver I will run a test for a long time to se 
what happens and  if it reboots.

Thanks.
Ramiro.
