I just installed gnuradio on my macbook and I wanted to test the usrp but got the same error as Sam:
@ enter_search 802_15_4_pkt: waiting for packet usrp_basic_rx: failed to start end point streaming Next I tried to use the benchmark_usb.py file and I got this error: Testing 2MB/sec... usrp_open_interface:usb_claim_interface: failed interface 1 usb_claim_interface: couldn't claim interface usrp_basic_tx: can't open tx interface Traceback (most recent call last): File "./benchmark_usb.py", line 106, in ? main () File "./benchmark_usb.py", line 96, in main ok = run_test (rate, verbose) File "./benchmark_usb.py", line 63, in run_test usrp_tx = usrp.sink_s (0, tx_interp) File "/usr/local/lib/python2.4/site-packages/gnuradio/usrp.py", line 230, in __init__ fpga_filename, firmware_filename) File "/usr/local/lib/python2.4/site-packages/gnuradio/usrp1.py", line 932, in sink_s return _usrp1.sink_s(*args) RuntimeError: can't open usrp1 Interestingly, the firmware is uploaded successfully, i.e., the led first blinks fast, then slower, and then I get the error. Any ideas on what might be wrong? Thomas On 7/27/06, Michael Klass <[EMAIL PROTECTED]> wrote:
Thanks for the reply Jon. I'm quite sure that it has USB 2.0 ports, though. On 7/26/06, Jonathan Jacky <[EMAIL PROTECTED] > wrote: > > I'm using OS X.
