a good catch. Can you forward it to the libusb maintainer?

@Thierry: any news on freeBSD? The same problem should occur as it has
here solved the getstring problem too (for ups.{model,mfr}

I think this second one is due to the fact that notification do not work
Can you send back a debug (level 3 == "newhidups -DDD") output, also
exporting USB_DEBUG=3
