Re: [Discuss-gnuradio] Is WUBI (Lucid) a viable environment for GNU-Radio (3.2.2) ?

2010-09-21 Thread John Shields 
Thanks Eric, will do though I used the sealed one given by Ettus but 
stranger things have happened.


I had also wondered about whether the USB ports on my laptop were running 
fast enough and before I posted, have confirmed "Enhanced" in the Host 
Controller description.


I wonder if U is underun and O is overrun? I briefly looked at the source 
but am not familiar with GNU_Radio and it's classes.


Thanks again for your suggestion,

   Regards,

John

I passed 'make check' correctly

I have my username in the group usrp

j...@ubuntu:~/gnuradio$ ls -lR /dev/bus/usb | grep usrp
crw-rw 1 root usrp 189, 132 2010-09-21 11:14 005

when I execute ./usrp_benchmark_usb.py I get:


Testing 2MB/sec... gr_vmcircbuf_createfilemapping: createfilemapping is 
not available
/home/john/.gnuradio/prefs/gr_vmcircbuf_default_factory: Permission 
denied

uUuOuUuOuUuOuUuOuUuOuUuOuUuOuUuOuUuOuUuOuUuOuOuUuOuUuOuUuOuUuOuUuOuUuOuU^Z


and it hangs so I kill it

[1]+  Stopped ./usrp_benchmark_usb.py

I cannot repeat this operation as I get

Testing 2MB/sec... usrp_open_interface:usb_set_alt_interface: failed
could not set alt intf 0/0: Connection timed out
open_nth_cmd_interface: open_cmd_interface failed
usrp: failed to load firmware /usr/share/usrp/rev4/std.ihx.
Traceback (most recent call last):
  File "./usrp_benchmark_usb.py", line 106, in 
main ()

  snip.


Just to rule out a flakey cable, can you try using a different USB 2 
cable?
