Dear all:
I have two laptops: one with gigabit ethernet and another one with 100Mbps
ethernet. I bout a USB Gigabit dongle (
http://www.amazon.com/gp/product/B0095EFXMC/ref=oh_details_o00_s00_i00) to
connect my non-gigabit laptop to the USRP. After setting up the drivers and
the correct network parameters, I am able to ping the USRP. However, when I
try to run the benchmark_rate example, I get this error:
Creating the usrp device with: ...
Error: LookupError: KeyError: No devices found for ----->
Empty Device Address
The laptop has USB 2.0.
I thought that the problem would be the dongle. Nevertheless, when I try
the dongle in my gigabit laptop, the example works just fine. Both laptops
are running linux.
Does anyone know what might be the problem?
I want this to work because one of the members in my team wants to get an
ultrabook without ethernet port, but with USB3. So we figured that the
dongle could work. Any help is appreciated
Thanks!
- Fernando

Are you explicitly
specifying the device argument, or relying on "discovery" to discover
your USRP device?
What happens if you're explicit about device
address?
What happens when you use:
uhd_usrp_probe --args
"addr=192.160.10.2"
Have you configured the USB-based-ethernnet port
appropriately? Does it have the correct subnet address attached to it?

I was relying on the discovery feature.
When I try uhd_usrp_probe --args "addr=192.160.10.2", the non-gigabit
laptop finds the usrp succesfully. All examples work fine when I add the
explicit address.
Why doesn't the gigabit laptop need it though? I used the usb dongle on the
gigabit laptop and it could run the examples without the explicit arguments
Thanks!

Since I can't see the total configuration of
your systems, I can't answer that question.
The discovery mode
requires that broadcast packets work properly, and I think it will only
query the first ethernet interface it finds by default.
I generally
tell people to use explicit addressing. It's a good habit, and once you
have more than one USRP on your system, it becomes mandatory.

Thank you guys for your help. I'm modifying the code to incorporate
explicit addressing.
Is there a way to extract the IP address of the USRP device using the
multi_usrp interface? Assuming I use the auto-discovery feature, how can
get the IP address of the device given by
uhd::usrp::multi_usrp::make(hint); where hint is empty?
I was looking at get_usrp_rx_info but it wasn't very clear as to how to do
it.
Thanks

You should use the device discovery API -- uhd::device::find().

Hi,
I experienced this adaptator on windows 7 64b (since I didn't find the drivers
for Linux)
and the performances
was very poor :
- ping to the usrp works
- a small sampling snapshot works if the bandwidth is not very high but if
didn't work for
Fs=50MHz, sc8.
- the streaming didn't works for Fs > 12.5 MHz, even in sc8 (packet loss). When
I look to
the network performances,
it reach only 25% of gigabit.
I thought that this adaptator was not very good since I test before an usb2
adaptator and
it reach 450 Mb/s which is
the theoretical performance of usb2.
Since you solved your problem, do you experience the same thing with this usb3
adaptator ?
Where do you find the linux drivers ?
Thanks.
Olivier
