Uhd_find_devices cannot find my B210

Hi,
I received my B210 this morning and when I run uhd_find_devices, it say
it can’t find any devices.

$ uhd_find_devices
linux; GNU C++ version 4.8.1; Boost_105300; UHD_003.005.003-0-unknown

No UHD Devices Found

lsusb shows the device, but the product id is different to what is in
/lib/udev/rules.d/40-uhd-host.rules

Bus 003 Device 006: ID 2500:0020

So I added a line to the rules file
SUBSYSTEMS==“usb”, ATTRS{idVendor}==“2500”, ATTRS{idProduct}==“0020”,
GROUP:=“usrp”, MODE:=“0660”

I reloaded udev, unplugged and replugged in the device, but still
uhd_find_devices can’t locate it.

I have the B210 plugged into a Via VL800 USB 3.0 card. lspci identifies
it as Device 3483 (rev 01).

What step am i missing?

Thanks,
Greg

You need to most recent version of UHD. Support for B210 was introduced
at 3.5.4 of UHD, and if you’re going to upgrade, you should upgrade to
the latest.

I added the Ettus repo and installed 003.007.001 and yet when I run the
uhd_find_devices command it shows the 003.005.003 version.

Do you recommend building from source?

Thanks,
Greg

I recommend erasing your installed-from-standard-repos instances of uhd
and gnuradio before installing the Ettus stuff.

sudo apt-get purge uhd uhd-host
sudo apt-get purge gnuradio

And then re-do the install-from-Ettus-repos.

You seem to have an old, residual version installed. Can you search for
packets that start with uhd and verify you’ve only got things installed
that come from the ettus repo?
Also, after adding the repository, you most probably have to update your
package cache.
