Hey! I installed the software and all tests ran OK. I have an USRP and I ran the benchmark "test_usrp_benchmark.py" and almost every time I start the script I get another result. Sometimes 4MB sometimes 16MB but never 32MB.
I´m using an DELL Inspiron 8100 with 512 RAM, 866MHZ Mobile PIII and USB 2.0 PCMCIA could this be the problem?
