[Discuss-gnuradio] usrp2 with atl1e gigabit ethernet device

[Christopher Friedt]

Hi list,

I've connected a USRP2 to my laptop's gigabit ethernet [1] and the
USRP2's ethernet indicator LED is not on. Running find_usrp2s returns
zero results on my machine, while on another machine, using the same
cable, the USRP2 is detected.

I've read that some people have actually had it working well with the
same gigabit ethernet device [2] and was hoping that someone else
could say what the problem is here. My first instinct is to assume
that the auto-negotiation process [3] is not working. It used to be
the case, that if auto-negotiation was not working, a crossover cable
would fix the problem. Does that sound like an accurate diagnosis /
prognosis?

Rather than buy a new cable, I might be able to add a bit of code to
the kernel driver to allow for manual switching through a /sys entry
(if the device supports such control operations), but I thought that I
would ask the list for suggestions first.

Cheers,

Chris
