For manufacturing and testing, there is a need to talk to
whatever device is connected to a given port on the host. This
change modifies adb's "-s" option to take either a serial
number or a device path. The device paths of the connected
devices can be listed using "adb devices -l" whose output
will resemble:
List of devices attached
016B75D60A00600D usb:2-5 device
3031D0B2E71D00EC usb:1-4.3 device
The second column lists the device paths. If the -l option is
not given, the output from "adb devices" will be the same as
it used to be (i.e. the paths will not be printed).
The device path can also be obtained with the get-devpath
command:
$adb -s 3031D0B2E71D00EC get-devpath
usb:1-4.3
Note that the format of the device paths are platform dependent.
The example above is from Linux. On OS-X, the paths will be
"usb:" followed by hex digits. For other platforms, the device
paths will be printed as "????????????" and the -s option will
not be able to select a device until someone implements the
underlying functionality.

FreeBSD (and other systems as well) may use libusb to work with USB devices.
libusb is integrated in FreeBSD base system in recent builds (8.0+),
however in other systems it may need include libusb.h like <libusb/libusb.h>
and install library from devel/libusb port or other repository.
Submitted change not supports events (attach/detach) as libusb 1.0 lacks
such functionality and in order to make code more portable I've not used
workarounds as in earlier changeset.
Code was tested on FreeBSD 8.0-RC1, HTC Hero (1.0.0.A6288, Android 1.5)
