Is there only one line of output that says No USRP2 found, or are there

I do “sudo find_usrps” and I only get one line of output that says No
found. I have tried both the binary and the git builds, but for the rest

I have reached a point that I am almost certain there is something wrong
on the USRP2 side. The LEDs look fine though (6 of them flash at
startup, 2 remain on).
It is extremely unlikely that there is nothing wrong with your USRP2, as
they are all 100% tested before shipping. There are many other
Is the USRP2 connected directly to the ethernet card? Are you certain
is a gigabit ethernet card? Can you send the output of dmesg after
connecting the USRP2? Do you have a TTL serial adapter?
I have connected the ethernet card (which is a gigabit one) directly to
USRP2 and assign a manual IP using “ifconfig eth0 10.0.0.2.”
This is the output from $lspci | grep Ethernet:

The output from dmesg | egrep ‘(eth0|Intel)’ after connecting to USRP2:

Please note that with the original SD-card, despite the lights being on,
don’t see anything going out of my machine when I call find_usrps (using
wireshark). But when I connect the USRP2 to my laptop without the
the light on the ethernet interface on the laptop goes on and for every
to find_usrps I can see an ethernet packet going out (on wireshark).
As a last resort, I tried to reprogram (a new) SD card. I followed the
instructions on USRP2FAQ and copied txrx.bin and u2_rev3.bin on the new
SD card. This time, even the LEDs don’t light up, and of course I still
cannot connect to the USRP2.
Then you did not copy the files correctly. You’ll need to follow the
instructions again, as those instructions work. If the LEDs don’t light
then the files are not on there and nothing will work.
I will re-do this with a new SD-card and report the results.
How do I know which version of firmware and FPGA bitstream I should use?
Is there a u2_rev4.bin available (since my USRP2 is revision 4)?
Any hints on what I might be doing wrong?
No, rev3 and rev4 use the same .bin files.
I highly appreciate your time.
