Rewrote the program to use poll instead of select (which does fit
libusb better even if I like select better generally)
nothing else changed only poll instead of select.

=> Works like a charm

So to sum it up: select + libusb seems not to work, poll + libusb works however.

So is this a general FreeBSD select vs. poll issue or just with the USB stack?

How can I help debug this further?
