Also, it used to be that I needed to be in the “usrp” group in order to access
the USRP.
Now i deleted this group and i still have access to usrp (even when the source
is not a uhd one but a usrp source)!
My understanding is that if i use the uhd device then i can do that
(ie, don’t need to be in the “usrp” group) but it seems to be happening even
with the usrp source.
What am I missing?
Merely deleting the “usrp” group from group file doesn’t do anything until you
log-out/log-in again.
yes I did logout/login (even rebooted the system to make sure)…

Well, in that case, probably your “UDEV” rules create the device world
read/write.
Check /etc/udev/rules.d/*usrp.rules

It depends on your udev settings:

The udev instructions I put in the UHD manual set the device wide open
to anyone on the system.
