Yes, I think it is.
I thought it was something else because usbconfig didn't see the device.

The libusb10 interface - I didn't write the code (the vendor supplied a Linux version that was trivially compilable on FreeBSD).

I have the source code and I can see what the issue is so I'll fix that, although I am surprised the limit for USB devices is so much lower than the system limit for file descriptors generally.
