Thus Linux definitely behaves differently here. My question is: Can and/or should FreeBSD be fixed to allow libusb_reset_device() as a user or should a driver library be fixed to not use that call.
This is an architectural problem. USB devices may have interfaces with independent drivers attached. If one USB interface driver is running as root and another USB interface driver is running as non-root, it doesn't make sense that the non-root device driver should be able to affect the root-one. Your LimeSDR device appears to be very simple, having just one USB device driver attaching to it. Just imagine some web-page trying to reset your USB device, just because it can! Yes, USB is also exposed to firefox nowadays :-)
What we could do is to add a sysctl which controls the behaviour for this specific case. Would that be of any use to you?
