Yesterday I made a VM with Ubuntu 10.04 and installed gnuradio
(3.6.5.1).
*uhd_find_devices is working fine *
$ uhd_find_devices
linux; GNU C++ version 4.4.3; Boost_104000;
UHD_003.005.003-123-g1c391767
– UHD Device 0
Device Address:
type: usrp1
name: node_4
serial: 4d9e2cab
*lsusb gave this *

What does it mean by “Bad Address”
Yesterday it was running fine. Any pointers ?
I tried resetting usb port with a custom script but that dint help.
Rest other scripts are working fine. bencmark_tx, benchmark_rx
everything
working. Only uhd_fft is painful.
Strange thing is that when I made a grc for viewing fft with QT, it is
working well without any errors.
