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

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.
From: Richard Meston
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
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!
