I am trying to use the USRP echotimer block from gr-radar module. But when I run the flowgraph containing this block, I get the following error:

You may be better served by cross-posting this to the discuss-gnuradio
mailing list, where there may be more users of gr-radar than here.

Generally, a "late command" isn't a fatal error.  What it basically
means is that the application (gr-radar) asked for a "timed" command,
but was unable to deliver that command before the time requested.

I noticed in the log that the device was B210 operating over "USB 2". This
is generally not a good thing.  It should be operating over USB 3.

Rob

It depends.  It's perfectly willing to operate over USB2, albeit at
lower sample rates.

Whether that's adequate depends entirely on the application...
