Re: [Discuss-gnuradio] gqrx segfaults: rtlsdr_read_async returned with -5

[M Dammer]

I cannot see anything being wrong with USB. I tried different Kernels,
different Dongles and they all fail. However booting my live DVD and
starting gqrx (32bit) works.
It looks like some incompatibility between the latest gqrx and my
systems :-(
