[Discuss-gnuradio] failed to find usrp[0]

[Pacho V]

hi everybody,

i'm a new user of the USRP and have encountered the following problem. when 
trying to run 'test_usrp_standard_tx' i get the following messages:

        usrp: failed to find usrp[0]
        die: lt-test_usrp_standard_tx: usrp_standard_tx::make

i'm using a quite recent version of mandriva, i installed python and wxpython 
using the package manager available from the distribution. all the other 
needed packages (gnuradio-core, etc) were installed in one subdirectory of my 
home directory. to do that i used

        ./configure --prefix=$HOME/gnu-radio --enable-maintainer-mode

the installation went more or less alright. when doing 'make check ' i got the 
message that Numeric couldn't be loaded. i decided to ignore this message 
since typing 'import Numeric' inside python worked fine.

the usb connexion seems to work smoothly: 

        Jan 20 04:29:41 localhost kernel: usb 3-2: new high speed USB device 
using 
ehci_hcd and address 73

can anyone suggest how to identify the problem? thank you very much for your 
answers.
