I am running ubuntu 11.10 on VMWARE FUSION (on OSX 10.7) and I have installed gnuradio 3.5.3
we have two laptops, each with their own usrp. They are connected to the usrp via USB.
We are trying to sent a packet of data but there appears to be a usb problem.
The other computer runs the "./benchmark_tx.py" program and sends it to the usrp and sends it wirelessly to the air.
My computer has the same set up except I am using "./benchmark_rx.py" in an attempt to receive the stuff
from the "benchmark_tx.py"
It tells me that the USB is lacking the proper permissions. The program begins running and none the the data is received.
What can be done about the permissions problem?
I have tried installing ubuntu as a separate partition on my mac, by following the instructions on the ubuntu website. It doesn't work, so VMWARE fusion is the only way I can get ubuntu to work.
ps.
I've tried installing gnuradio 3.3.3 via macports (on an OSX 10.6 parition). when running "./benchmark_rx.py -R B -f 2.45G" I get a different error. A real time scheduling error. No idea what that means.
Tried adding sudo (ie. "sudo ./benchmark_rx.py -R B -f 2.45G") and found a different error. It claims that module gnuradio does not exist.
I've checked the ".profile" file that macports created, and added the paths specified on this website
(http://www.oz9aec.net/index.php/gnu-radio/gnu-radio-blog/373-gnu-radio-330-on-mac-os-x)
i've tried running python in terminal and entering "from gnuradio import gru" and it doesn't complain about anything.
I would really appreciate some help. Hope to hear back from you soon
