[Discuss-gnuradio] find_usrps only succeed when an sniffer is ON

[Jorge Miguel]

I installed GNU Radio on a ThinkPad Lenovo T4410 under Ubuntu 10.04.
After connecting the USRP2 with the original Ettus code on the SD card D and F LEDs are ok and when executed:

~$ sudo find_usrps
No USRP2 found.

I run wireshark or tcpdump to see what happens in my network and I got:

~$ sudo find_usrps
00:50:c2:85:35:a2 hw_rev = 0x0400

If I stop the sniffer, I get again:

~$ sudo find_usrps
No USRP2 found.

My problem is that 'find_usrps' only works when a sniffer is running. How can it be explained?

Jorge,
