	Unfortunately, the only thing I can suggest is to crawl
through the code and see what it's doing wrong. In particular, instead
of reading numPorts out of 'ci', you may want to try reading it out of
'ur', where it really gets put.

	Actually, ColdSync has two interfaces to USB: the first is
*BSD-specific, comes as part of FreeBSD, and uses
/usr/include/dev/usb/usb.h. The second uses the more portable "libusb"
package, which is available as a port.
	Evidently you don't have libusb installed ('configure' should
have found automatically it if it was), but you've told it to use it
anyway, and to use the wrong include file.

	If you want to use "--with-libusb", you're going to have to
install the libusb port.
