Dear Rahul The program test_fusb is not installed in the computer's path. I can be found in ../usrp/host/apps along with several others such as test_usrp_standard_tx and test_usrp_standard_rx. In all three cases these programs are invoked by navigating to the ../usrp/host/apps directory and typing:
./test_usrp_standard_tx The "./" means execute the program in the current directory and not to search the computer's path. You can see your path with the command "echo $PATH" from a terminal prompt. I have been recently using usrp_siggen.py instead of test_fusb or test_usrp_standard_tx. This Python scipt is in gnuradio-examples/python/usrp along with a couple of others such as usrp_oscope.py which I havent quite gotten to yet. All of these load the firmware.ihx and usrp_fpga.rbf files and change the blinking led #0 from once a second to twice a second or so. The usrper program is in the path, but it doesnt load either firmware.ihx or usrp_fpga.rbf. However, once the firmware.ihx and usr[_fpga.rbf file are loaded then the command 'usrper led1 on' and 'usrper led1 off' should produce visible results. Currently, I can run usrp_siggen.py with no problem and change the frequency and amplitude of the resulting sine waves and admire them on a scope. I will be here working through some Python details for the next three days and if you look at the previous post, it is a combination of usrp_siggen.py and my current thoughts, in an *almost* operational program. It will load firmware.ihx or usrp_fpga.rbf if requred. When its window is closed, then the original usrp_siggen code executes sg.start and starts the default 900Khz sine wave at a volt or so amplitude. I hope this helps you a little bit. Please let us know your progress as you work through the issues.
