Hi Ralph, libusb_get_version() was added I believe around 1.0.10?
It's wrapped in a logging enabled flag so if you disable logging then maybe it will get past it: https://github.com/Nuand/bladeRF/blob/009d8181e0799f3b8e282e22f6ac793ac9b85f85/host/libraries/libbladeRF/src/backend/libusb.c#L525 I'll take a look at how we can help fix that on our end. Try updating libusb(x) in the meantime? Brian On Fri, Dec 13, 2013 at 12:25 PM, Ralph A.
