I was trying to capture samples from two USRP2s by using MIMO cable with
shared mode i.e. only by a single Gigabit ethernet cable
connected to the PC but I am only getting samples from one of the USRPs. I'm
using the uhd example rx_multi_samples.cpp for testing. I attached the
code that has some modifications done on it. Could you please help me on
capturing samples from both USRPs. Thanks.

Hey All,
I'm playing around with different versions of the released UHD. I have a
simple flowgraph in GNU Radio with a USRP source and sink. and the TX and
RX are looped together. I'm trying to just get dataflow through the USRP.
UHD 3.7.1 seems to work great. The signal I send to the USRP matches what
the USRP sends back to GNU Radio, great! But in UHD 3.7.2 and 3.7.3 the TX
LED is red instead of green and I appear to just be getting noise back to
the host. What exactly does the RED LED indicate (I'm sure it's bad)? In
all cases, I run the uhd_usrp_probe utility tool and no significant errors
result from that. I'm not sure what I'm doing wrong.
Thanks,
Ryan Marlow
