What version of NetBSD are you running?  It sounds to me very much like 
the "no buffer memory problem", because the kernel doesn't have enough 
contiguous memory for a USB drive and the driver doesn't know how to 
use non-contiguous memory.  2.0beta and -current print an explicit 
message about that; I don't think 1.6.x does.

The simplest bypass is to make sure the device is plugged in at boot 
time.  Others report success with various uses of "dd" to flush memory; 
I've had mixed results doing that.
