Subject: | [Discuss-gnuradio] FW: USB problem with USRP |

Hi all Resolved this problem – it appears
to have been a library conflict. I’m not sure which one, but having
re-installed some of the libraries in different locations and making sure the
build uses the correct libs it now works OK. Rich From: Richard Meston Hi I’m trying to get the USRP to work, using the
test_usrp_standard_tx program, but am not having any luck. On execution, the flashing LED on the USRP goes out, and
there is a delay of about 3 seconds on the PC, then the following message
repeated: Usb_control_msg failed: error sending control message:
Connection timed out Followed by: Usrp: failed to load fpga bitstream
/usr/share/usrp/rev4/std_2rxhb_2tx.rbf. In USBView I see the device as a 480Mbps USB2 device with
VID FFFE, PID 0002 and Rev 0004 (both before and after running the above app).
If I manually try using fxload after a power cycle of the USRP board
(e.g. fxload –t fx2 –D /dev/bus/usb/03/019 –I ./std.ihx) then
the flashing LED goes out, but I get no other indication that things have worked. I’m running this on a Fujitsu Lifebook, running
Mandriva 7. I’ve tried searching the gnuradio docs but can’t
find anything that mentiones the “Connection timed out” error
above. Any help would be greatly appreciated! Cheers Rich |
