Maybe you should have a look at /usr/local/share/usrp where the .rbf
files that get downloaded to the USRP are? Try specifying a .rbf file
when you initialise the USRP in your script.
I'm just guessing a bit here.

Hello Sebastiaan,
Thanks a lot for your prompt answer. Yes I am using Ubuntu and I
execute the scripts as root. However, I also configured once the
access for another user in the system called default. So the commands
you suggested look like:
$ cat /etc/group|grep usrp
usrp:x:1002:default
$ cat /etc/udev/rules.d/10-usrp.rules
ACTION=="add", BUS=="usb", SYSFS{idVendor}=="fffe",
SYSFS{idProduct}=="0002", GROUP:="usrp", MODE:="0660"
The thing is that I can use the same gnuradio installation with a
different USRP and it works, so I would say this is a USRP problem
rather than a permissions problem.
There is also this issue with the LED only blinking at higher speed
and never slowing down that I mentioned in my email to the list. What
could be happening?
Best regards
Natalia Olano
