Im having the same problem. You installed from package? I removed the package and am currently building from the git repo to see if that clears it up.

Although there is no difference when I run the command via root. I've also read and applied the advices in hackRF's FAQ about this error, but again there is no change. How can I troubleshoot it to find the cause? I'm using hackRF One (Board ID number 2, firmware 2014.08.1) on Ubuntu 14.04 (Overall it works fine and for the test, I managed to get a FM station with gqrx, but it always needs me to run every command like 'gqrx' twice, to be able to use the hackRF) Update: I also tested DFU boot (with the hackrf_one_usb_ram.dfu file), but dfu-util gives me this in the end: "Device returned transfer size 2048 DFU CRC does not match Unsupported DFU file revision 0000" Thanks Mehdi
