I am having a similar problem.  I used ethtool to disable the pause
parameters for this interface; here is the output:
sudo ethtool -a eth1
Pause parameters for eth1:
Autonegotiate:  off
RX:             off
TX:             off

But I still get this error when i run tx_samples: 
sudo ./tx_samples -e eth1
terminate called after throwing an instance of 'std::runtime_error'
  what():  Unable to retrieve daughterboard info
Creating USRP2 Object.... Aborted

I'm running the latest version of GNU Radio (freshly re-complied this
morning, revision 10644) on Ubuntu 8.10.  I have a USRP2 with the firmware
and bit file that was complied on March 15th 2009 and the xcvr2450
daughterboard.

Are there any other ideas as to what could cause this (or did I disable flow
control pause wrong)?  Thanks!
