This is kinda strange.  Obviously, libusb can talk to it when it comes
to getting at the serial number but not much beyond that.

I have no idea about the libusb implementation for OSX.  Years ago, I
had similar issues with FreeBSD that turned out that libusb didn't
have the flag set in the request that allowed to get short replies
(less than the requested size) to be passed up.  That has been fixed
in the official libusb quite some time ago though.
