[Discuss-gnuradio] usrp not found until power cycled

[Jiri Pittner]

Hi all gnuradio enthusiasts,

I just obtained a brand new USRP and it seems to work fine (so far WFM via 
TVRRX tested),
however, after the python script ends, fffe:0002 disappears from lsusb
and gnuradio cannot find the USRP until I cycle the usrp power.
I am running gnuradio 3.0.2 on a up-to-date gentoo with 2.6.21 kernel.
All other USB devices seem to work fine.
Is this problem already known? Could it be a problem of USRP firmware, or
should I search rather in the computer?

Thanks for advice,

Jiri
