Hi all,

I've got a uhd git checkout (the cmake build system gives version
UHD_003.20110324014830.95b966a ).

I've an atom-based 32 bit machines with two ethernet devices.
eth1, whose address is, is directly connected to
a N210, whose address is

The device is correctly responding to a


This is the result of a uhd_find_devices:

# uhd_find_devices
linux; GNU C++ version 4.4.1; Boost_103800; UHD_003.20110324014830.95b966a

Device discovery error: unknown key format: addr
No UHD Devices Found

Connecting the same device to another server, it correctly
reports the device data as following:

# uhd_find_devices
linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.20110324014830.95b966a

-- UHD Device 0
Device Address:
    type: usrp2
    serial: E2R11YCUP

Does anyone know what is going on? If further details are
needed I will be more than happy to provide them.

Thanks in advance!
