  Everytime I run a (v3.0.2) gnuradio program (on NetBSD 3.1), I get the
  following message:

  usb_control_msg failed: error sending control message: Input/output

I haven't tracked this down, but I'd be interested in fixing it.  I
suspect it's either something missing in NetBSD or some OS-dependent
code that isn't properly abstracted.  I think it might be coming from
libusb, but I really don't know - the error message is a bit lame.  If
you can figure out the call chain that results in the error (perhaps
with ktrace on the simplest program that provokes it), that would be

BTW if you run -current instead of 3.1, the USRP should do 16 MB/s
each way instead of 4 MB/s that you probably get on 3.1.  The
improvements were committed sometime this summer.
