Hi,
I'm running GNU Radio 3.3 from within a Fedora 12 x86 64-bit virtual
machine using VMware Fusion on Mac OS X 10.6.4.
I've configured a second ethernet interface, and tested communications with the
USRP2 using the following command
find_usrps -e eth2
Now, the thing is other commands
They refer to version specific code for libusb (v0.1 or v1.0). Most of
the code is made common between versions, but the remaining parts are
in those files. Which file is compiled is determined by configure and
will depend on your system setup.

What's the benefit of using UHD, at the moment? I thought that was something
that was being developed to better integrate with the National Instruments
hardware ecosystem.
Eventually it will incorporate all the hardware with full functionality

I have looked everywhere, including through the Verilog FPGA code and in

According to usrp_fft.py, the -8 and --no-hb options should allow a

Dont blow up on me like the last guy... but the usrp2 gnuradio driver
uses a linux kernel-specific packet ring and will only build on linux.
Hence the error message that you saw.
However, the UHD uses userspace udp sockets and will build on macos and
windows as well. You may want to try:

Hi,
I'm using Mac OS X 10.6.4 and I'm unable to build the USRP2 component on

what is the different between usrp_prims_libusb0 and usrp_prims_libusb1?
what case are they used?

I pushed some changes to the uhd master that will check the deviation on
the times between boards. This should help you to debug your setup. If
you see an error message like the following, then you may have an issue
with the configuration. In the following example, I disconnected the PPS

Alex,
You are right. "Auto T/R" is the right option to use. One little thing, the
usrp source/sink block takes a parameter "gain(db)", what is the maximum value
that I can specify here? Is it 32db? Also, what maximum amplitude value I can
specify in signal source block? Is it 32767?
Thanks.

Hi,

I must say, for a new user, documentation is lacking for the hardware.
I searched the web for some info on setting up the hardware, just in case, but
found none, so opened it up and installed the card.

If I were to use the USRP2 + WBX module to receive FM broadcast
