-- Opening a USRP2/N-Series device...
Error: RuntimeError:
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected protocol compatibility number [7 to 11], but got 12:
The firmware build is not compatible with the host code build.

ということで、FPGAイメージとファームウエアのアップデートが必要？
