Apparently, libusb couldn't find any devices.

What happens if you add "-u root" to the command line?

Also, prepending USB_DEBUG=3 to the command may shed some light on
what libusb is doing.

I don't have first-hand experience with libusb in *BSD, but from what
I can gather, the uhid driver can block libusb access to HID-class
devices. (I wouldn't be surprised; this happens in OS X, and to a
lesser extent, in Linux as well.)

There is a thread on the libusb list now (also referring to 0.1.10a):

but nothing conclusive has been posted.
