Please check dmesg to see if there are any power limit issues. If the bladeRF 2.0 is running on USB 2.0 it may not be able to request enough power.

Otherwise, "No Device Available" is a sign that bladeRF-cli (or another program) is using the deivce. Please ensure you exit bladeRF-cli; the bias-tee setting will not carry over to GNURadio. You will have to set "bladerf=0,biastee=tx" in the device string in gr-osmosdr. Or if you're using gr-bladeRF, please ensure to enable Bias-Tee in the sink block.
