[Discuss-gnuradio] cannot detect USRP2 on ubuntu 9.10 whatsoever...various solutions adopted...

[yulong yang]

Hi all,

I am new to gnuradio and stuck with the usrp2 connection for several days... I looked up tens of search results but no solution yet. Therefore I post my problem and hope someone could give me a hand:

I am running gnu radio 3.2.2 on ubuntu9.10, and I think gnuradio works fine because dial_tone.py and grc all could be launched correctly. However, when I plug in USRP2, problems happen:

if I typed in "sudo find_usrps" it says: No USRP2 found.

if I typed "sudo find_usrps -e eth0" it also says No USRP2 found. (eth0 is what I get when typing in ifconfig)

if I typed in "sudo usrp2_fft.py" t says:

Traceback (most recent call last):
  File "/usr/local/bin/usrp2_fft.py", line 273, in <module>
    main ()

    return _usrp2.source_32fc(*args, **kwargs)
RuntimeError: No USRPs found on interface eth0


What exactly the problem is?
TO note:
1. python is fine. I ran following process and it did not say error:
  Python 2.6.4 (r264:75706, Dec  7 2009, 18:45:15) 
  [GCC 4.4.1] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  >>> from gnuradio import gr
  >>> from gnuradio import usrp
  >>> from gnuradio import audio
  >>> from gnuradio import usrp2
  >>> exit()

2. could it be the firmware in usrp2? I saw some threads discussing firmware in SD card. But it seems to run process like usrp2_fft.py dose not need any firmware.

3. my usrp2 runs fine. I checked it with another computer which could launch usrp_fft.py correctly. Also, when I power on usrp2, all 6 lights flah and then D and F remain on.

4. my ethernet card should be fine. it is gigabit. here is what it says when I type in "sudo ethtool eth0":

   Settings for eth0:

I am really confused and find no solution on my own. Any suggestion would be greatly appreciated. I will wait online and provide any additional information if you need.
