13.2 USB Cable Association for Certified WUSB

The Certified Wireless USB specifications define two types of methods of associating
(also known as pairing):

Numeric association: Also called in-band because it uses WUSB wireless
communication.

Cable: Uses other means to associate two WUSB devices.Currently, only one
out-of-band association method is supported in the specification. This is
USB Cable Association, which uses a USB cable to connect two devices and
allow them to associate.

The UWBTracer/Trainer™ analyzer can capture and use the USB Cable Association
traffic for recording and decrypting Certified Wireless USB traffic. This is done with the
help of the optional USB Analyzer plug-in module (US007MA), which should be inserted
into the left-side slot. (The right-side slot has one of the UWB Analyzer plug-in modules.)

The USB plug-in module is active and waits for USB traffic from the moment the analyzer
is powered on and ready for recording. By default, the module is configured to auto-detect
the USB speed. If you want to set the speed manually, you can use the recording options
settings (see Section 12.4, “Recording Options: USB Assoc.” on page 189).
