Thanks for the information Dominic. I looked at the schematic for HackRF and did some testing on it. I decided that it was well and truly dead and not (by me at least) fixable. http://www.seti.net/engineering/engineering.php I guess I’ll be buying another HackRF!

You can disable this by following instructions here: https://github.com/mossmann/hackrf/wiki/FAQ#power-saving-and-usb-autosuspend 2) There was an issue with start up on some boards that caused them not to come up first time. It primarily affected HackRFs from a specific manufacturing run and we were able to fix it in software. The fix was included in our 2018.01.1 release here: https://github.com/mossmann/hackrf/releases/tag/v2018.01.1 The fix is the only change between the 2017.02.1 and 2018.01.1 releases, so you can grab the binary firmware from the release archive and flash it without having to update your host tools. If you want to know more about the second issue, Mike wrote an in depth blog post on it: https://greatscottgadgets.com/2018/02-28-we-fixed-the-glitch/ There could be other issues affecting your system, but these are the two that spring to mind immediately.
