My B200 device runs well with UHD on the development head (version 3.13). I am trying to change it back to uhd3.10. I simply created a fresh new Linux environment with uhd3.10 installed. The installation is successful and it passed "make test". In the terminal window, this usrp shows on the list under lsusb command. I first ran uhd_find_devices and uhd_usrp_probe with no success. Finally, I ran uhd_usrp_probe and got the following result:
uhd_usrp_probe --args="fw=usrp_b200_fw.hex"
linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.000.HEAD-0-gef157678
-- Loading firmware image: /usr/local/share/uhd/images/usrp_b200_fw.hex...
Error: LookupError: KeyError: No devices found for ----->
Device Address:
fw: usrp_b200_fw.hex
However, if I switch back to the uhd version on the head, everything runs well.
Does anybody have any clues on how this version 3.10 problem occurs?
