Hi all,
I'm trying to use a B205 Mini on my Surface Book with Ubuntu 16.04 running
in a virtual box. When I press the reset button on the B205 mini itself,
and then run uhd_find_devices, this is what is returned:
~$ uhd_find_devices
[INFO] [UHDlinux; GNU C++ version 5.4.0 20160609; Boost_105800;
UHD_3.11.0.git-233-g25fc32af]
[INFO] [B200] Loading firmware image:
/home/iris/Documents/grprefix1/share/uhd/images/usrp_b200_fw.hex...
[ERROR] [USB] USB open failed: insufficient permissions.
See the application notes for your device.
[ERROR] [USB] USB open failed: insufficient permissions.

--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
serial: 3123C65
name: B205i
product: B205mini
type: b200
It is seeing the device even though the permissions error occurs. In the
past whenever I've run into these USB permissions problems, I copied the
uhd-usrp.rules file to /etc/udev/rules.d and it solved it. This time it's
not going away.
When I run uhd_usrp_probe I get this error:
~$ uhd_usrp_probe

I've run uhd_images_downloader to make sure I was using the latest image as
well. I'm not sure how to fix this.
