Re: [Discuss-gnuradio] Ubuntu "Feisty Fawn"

[Dave hartzell]

Hi all,

Is there a fix for this?  I think I'm experiencing it, and just
noticed that my SDR-IQ (annoyingly) also flaps on/off when plugged
into an Ubuntu 7.04 system (using the gnuradio 3.0.2-2 packages).

/var/log/messages reports the devices disconnecting and reconnecting
about every five seconds...

Thanks,

Dave
