[Hackrf-dev] ubuntu 14.04lts

Fri Jul 17 12:19:03 EDT 2015

Hi everybody,

i tried to use the installation script from Donald. Everything seems to work, so i don’t get any errors during the installation or so. 

But when i try to run the hackrf_info command i get the following error:

	Found HackRF board 0:
	hackrf_open() failed HACKRF_ERROR_LIBUSB (-1000)

Okay, i know this error could be from the missing dev rules. But they are all there. 

The real crazy part is: When i’m trying the command a second time, i get a correct output. 

	Firmware Version: 2014.08.1
	Part ID XXX
	Serial XXX

When i retry it: every next try works. But when i’m waiting 2 minutes, i get the same libusb error from above.

Can anyone help me with that? (i tried the hacker on my MacBook and it works fine so it should not be a Hardware Issue… )

Thank you!

Not sure if it's been fixed yet. But if you get it, its due to gqrx saving the gain settings and trying to apply the wrong ones when you load up the ettus board. The fix is to remove the gains=<blah> line from ~/.config/gqrx/default.conf

Me personalty I use packages, but I re-pointed my Debian machine from wheezy to jessie, so I at the cost of being behind on security updates (machine is not networked) I'm slightly closer to the cutting edge, but still behind  using  ppa:gqrx/(releases and snapshots), mostly because I did not know that it existed when I set the machine.
