[usb] Test Suites for USB Host

[Petar Bajic <pnbajic@yahoo.com>]

There is some "FuturePlus USB Preprocessor".
I have some text about it that says with it you can
use existing HewletPackard logic analyzer as a pasive
USB analyzer.
    ...The FuturePlus protocol-sensitive logic and USB
Transaction Inverse Assembler, coupled with the
advanced triggering and system performance software of
HP's logic analyzer, give the user a powerful tool in
debugging, testing, and verifying compliance of USB
periferials and USB-based systems....

There are some capabilities mentioned that you might
want yours to have too:
STATE ANALYSIS MODE
    allow you to trigger any address and end point,
    any data patern
    any data CRC
    any USB error
    bad or invalid PIDs
    you can store all of it
TIMING ANALYSIS MODE
    you can do analog analysis of these signals:
    - clk12
    - mdata
    - lbc_idle_state
    - pid_state
    - sof_or_adr_state
    - spf_or_ep_state
    - crc_state
    - pre_data_state
    - data_state
    - sof_tick
CROSS-DOMAIN ANALYSIS
    - view data from multiple buses simultaniously
    - view source code, code execution and
corresponding USB packet transfers simultaniously.
