Re: [Discuss-gnuradio] Is WUBI (Lucid) a viable environment for GNU-Radio (3.2.2) ?

[John Shields]

Thanks Eric, will do though I used the sealed one given by Ettus but 
stranger things have happened.

I had also wondered about whether the USB ports on my laptop were running 
fast enough and before I posted, have confirmed "Enhanced" in the Host 
Controller description.

I wonder if U is underun and O is overrun? I briefly looked at the source 
but am not familiar with GNU_Radio and it's classes.

Thanks again for your suggestion,

       Regards,

                John
