Hello all,
I have two USRP B210 devices which i use in my MIMO application. When
i use the two of them concurrently in a flowgraph - or different
flowgraphs - i notice that the signal received by the streams of one
of the devices (the one whose serial number is last in lexicographical
order) is distorted. Because i transmit a known training sequence, i
know what to expect, and i observe that sometimes the real or
imaginary part of the signal has flipped its sign (i see the signal
mirrored compared to the known one), or other times it is completely
distorted. When i use each device separately, everything works fine.
The UHD driver i use is the v3.9.5 one.Any ideas about it?
Thank you!

COuld you perhaps share a very-simple flow-graph that shows the issue?
What sample-rate are you using? Is this over USB-2 or USB-3?
