Hello-
I am having a usb/USRP issue under x86_64 Mandriva 2010.1 with
gnuradio-3.3.0.
I compiled and installed using the default procedure:
./configure
make
sudo make install
When I try to use usrp_fft.py, I get many errors (see below). The gui
pops up, but no data is displayed:
[matlis@localhost z.gnuradio]$ usrp_fft.py
fusb::_submit_urb: Bad file descriptor
_submit_urb failed
fusb::_submit_urb: Bad file descriptor
_submit_urb failed
fusb::_submit_urb: Bad file descriptor
.
. many copies of the error above, then…
.
fusb::_submit_urb: Bad file descriptor
_submit_urb failed
fusb::_submit_urb: Bad file descriptor
_submit_urb failed
fusb::_reap: Bad file descriptor
fusb::_reap: Bad file descriptor
I believe this is a distribution-specific error, as I was not able to
duplicate the issue on a different x86_64 Fedora 12 computer using
exactly the same installation procedure and USRP hardware.
Incidentally, I had to modify the udev rules a bit to get it to work
under Mandriva:
[matlis@localhost z.gnuradio]$ more 10-usrp.rules
ACTION==“add”, SUBSYSTEM==“usb”, ATTRS{idVendor}==“fffe”,
ATTRS{idProduct}==“0002”, GROUP:=“usrp”, MODE:=“0660”
ACTION==“add”, SUBSYSTEM==“usb”, ATTRS{idVendor}==“077d”,
ATTRS{idProduct}==“0410”, GROUP:=“usrp”, MODE:=“0660”
(email formatting broke up what where 2 lines originally)
Any thoughts?
thanks,
eric
