[Discuss-gnuradio] not responding B100

[Vincenzo Pellegrini]

Hi List,

My B100 suddenly stopped responding to UHD init.

It appears that the USB interface actually lost its ability to identify as a device.

Here below, you can find the output of the fedora "messages" log for

the Broken B100 as well as for a working one.

Could this be solved by re-programming the USB interface somehow?

my best regards 

vince
