[Discuss-gnuradio] Help: Can not pass the usrp_benchmark_usb.py test.

[burney bian]

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.
