Hello all.
I am using Gnuradio and bladeRF x40 and for long time it has worked fine and now when I start bladeRF with gnuradio it show me this in the terminal:

Does anyone have a solution to fix it ?

The info I got is:

bladeRF-cli version: 1.8.0
libbladeRF version: 2.4.0

Firmware version: 2.4.0-git-a3d5c55f
FPGA version: 0.12.0 (configured by USB host)

Board: Nuand bladeRF (bladerf1)
Serial #: "------------------------------"
VCTCXO DAC calibration: 0x99d1
FPGA size: 40 KLE
FPGA loaded: yes
Flash size: 32 Mbit
USB bus: 1
USB address: 8
USB speed: Hi-Speed
Backend: libusb
Instance: 0

Are there any USB related messages in dmesg? Are you using the USB cable that came with the bladeRF? Can you try to see if another USB cable helps?

Any update on this?
The issue is affecting me aswell. There is also an issue in github: https://github.com/Nuand/bladeRF/issues/849
