was the build configured with usrp1 support (what did cmake print)?

Hmm, I guess I should have looked at that output more closely.

The relevant output seems to be:

-- Could NOT find LIBUSB  (missing:  LIBUSB_LIBRARIES LIBUSB_INCLUDE_DIR)
-- Has USB support - not found
...
-- Configuring USRP1 support...
-- USRP1 support disabled by configure flag
--  Skipping USRP1 support.
-- Configuring USRP2 support...
-- USRP2 support enabled by configure flag
--  Building USRP2 support.

Where do I find the flag to enable USRP1 support? (if default install
behavior does not support USRP1, this should really be explicitly stated in
install guide...)

and

Why isn't my libusb install being picked up?
sudo yum install libusb ->
Package libusb-0.1.12-23.fc13.x86_64 already installed and latest version
Nothing to do

Thanks

Probably yes. Although, it will automatically enable if libusb support
is found. You may want to run cmake-gui and check the box, or specify
-DENABLE_USRP1=TRUE

did you install the development files for libusb1? the *-dev packages,
same as with gnuradio

-Josh

I decided to ignore what yum was saying and explicitly install the version
of libusb linked from http://www.ettus.com/uhd_docs/manual/html/build.html

Still it complained:

[foo@bar build]$ cmake -DCMAKE_INSTALL_PREFIX=/opt/uhd -DENABLE_USRP1=TRUE
../

-- Configuring incomplete, errors occurred!

Finally I tried:

cmake -DCMAKE_INSTALL_PREFIX=/opt/uhd -DENABLE_USRP1=TRUE
-DLIBUSB_INCLUDE_DIR=/usr/local/include/libusb-1.0/ ../

and this seemed to make cmake happy.

Now I'm on to:

/opt/uhd/bin/uhd_find_devices
linux; GNU C++ version 4.4.4 20100630 (Red Hat 4.4.4-10); Boost_104100;
UHD_20101109.230702.c0dfc2c

Warning:
Could not locate USRP1 firmware.
Please install the images package.

No UHD Devices Found

After some head-scratching I followed the README in uhd/images, using:
cmake -DCPACK_GENERATOR=RPM ../
make package
sudo rpm -i UHD-images-20101109.230702.c0dfc2c-Linux.rpm

Finally, uhd_find_devices found my usrp1.

Thanks for your help!

(10 minutes of adding a few more notes to the install guide could save hours
of answering questions from befuddled users like me in the months to come :)

Is that were fedora install the libusb1.0 package, or did you build
libusb1 from source?

See

http://code.ettus.com/redmine/ettus/projects/uhd/wiki#Downloads

http://www.ettus.com/uhd_docs/manual/html/images.html

I built it from source. libusb-1.0.8.tar.bz2

Right, I saw those sections, but it wasn't initially clear to me whether the
images/ stuff was "here's some info about the images should you ever get
interested in modifying that stuff" versus "you must do this if you want to
use your USRPs at all". I fail at reading comprehension, I guess :)
