Previously I had v3.1.3 installed. This was uninstalled (all packages 
removed) before installing v3.2 following the NetBSD build guide.

I looked at the v3.2 firmware. In 
gnuradio-3.2/usrp/host/lib/legacy/db_xcvr2450.cc line:375 the debugging 
output of setting reg is not commented out:

xcvr2450::send_reg(int v)
  // Send 24 bits, it keeps last 18 clocked in
  char c[3];
  c[0] = (char)((v >> 16) & 0xff);
  c[1] = (char)((v >>  8) & 0xff);
  c[2] = (char)((v & 0xff));
  std::string s(c, 3);

  usrp()->_write_spi(0, d_spi_enable, d_spi_format, s);
  printf("xcvr2450: Setting reg %d to %X\n", (v&15), v);

In the usrp2 firmware it is commented out.

Are the xcvr2450 boards supposed to be able to be used with the usrp1 ?
