Dear all,

I am trying to get my old USRP1 running again but unfortunately I cannot
receive properly. To test it I use benchmark_rate utility.
Whilst transmission seems works properly (no underflows or complaints),
the reception is not working. A lot of "D" appear, regardless the
sampling rate.

I am using UHD 3.9 LTS (but I am able to use my self-compilation from
git source).
The command I use is

benchmark_rate --rx_rate 500e3

and the output is

-- Loading firmware image: C:\CTTC\UHD\share\uhd\images\usrp1_fw.ihx... done
*** Warning! ***
Benchmark results will be inaccurate on USRP1 due to insufficient features.

Hi Pol,

Ds on USB2 are really really rare. I don't have a USRP1 to test here,
locally, but my first suspect would be your Operating System's USB
stack. Can you try to use the device on a different OS, maybe on a
different machine?

To try, you could download and burn the GNU Radio liveSDR environment[1]
to an USB stick, and boot just any PC with it. For your downloading
pleasure, I'd recommend either using the torrent file, or the eu2 Mirror
(which happens to be my server).

Best regards, and thanks,

Marcus

Are you perhaps running this inside a VM?
