You are right. I didn't add the configuration stuff because there was
a note somewhere in the code that it isn't necessary. Maybe that was
only true for Linux.

I'll add a call:

usb_set_configuration (devices[devcount].libusb_handle,

The check for interfaces and alt settings needs some work, too.
