Hi All,
I'm a newbie here. Recently, I got an USRP. But I can not make it work. Even
the exmaples of GNURadio doesn't work properly. Could you please give me
some help? Thanks.
I tried it on 4 PCs. None of them can pass 32MB/s usb test with
usrp_benchmark_usb.py.
Most of them can only passed 2MB/s test.
I tried 3 different USB cables. All USB ports on the PCs. So, where might be
the problem? How to make sure the problem is not in USRP box? The firmware
or hardware. By the way, I'm using Ubuntu 9.04.
1. Dell XPS 1330
2. Dell 640m
3. Dell Desktop
4. PC with Q6600, AsusP5KR, 4GB memory.
