Maybe the same problem occured in MacOS's libusb. Compare the following
posts:

https://github.com/myriadrf/LimeSuite/issues/253

https://discourse.myriadrf.org/t/limesdr-mini-with-freebsd/6230/7

In both cases there is an issue when calling the libusb_reset_device()
function.

The problem on MacOS seems to have been fixed according to this post:

https://github.com/myriadrf/LimeSuite/issues/253#issuecomment-480263517

Look at the following patch:

https://github.com/libusb/libusb/commit/a0b5d27fa7f2bba11965e2b70533f925a5772808

The patch seems to be darwin-specific. Is the same bug affecting
FreeBSD or is this a different issue? Can the problem be solved for
FreeBSD as well?


Kind Regards,
