Note that Windows may state that the driver is not certified by Microsoft. TI has verified that the
driver passes Microsoft’s HCT test setup, but to date has not submitted the driver for
certification. Any certification TI acquires will have to be performed again by target companies
prior to their specific product release due to regulations by Microsoft and the USB IF.
Nevertheless, TI is pursuing certification in the first quarter of 2005.
Because the VCP driver architecture contains two modules, one for the USB functionality and
one for the COM port functionality, Windows will present the “Found New Hardware” dialog
twice. For the same reason, you should be able to see the solution enumerate in two places in
the Windows Device Manager when installation is complete. For the Windows 9x driver, it
enumerates as a “VCP device” and also as a new COM port, as shown in Fig. 3.

Enumeration on Windows 98
For the Windows 2000/XP driver, it enumerates as a “multiport serial adapter”, and also as a
new COM port, as shown in Fig. 4.
