Not if you use the FTDI parts. *They* write the system driver, and
supply a complete driver package for 32 and 64 bit Windows. All the
application programmer needs to do is interface with it via an easy to
use .dll. The latest driver packages from FTDI are even signed. Here
at work I've used FTDI parts to embed a USB device ports in our
gadgets (including UHF radio receivers) for years now without any
heartburn. FTDI will even allow you to customize the driver package
(to "brand" the USB driver with your own company name and tailor it to
your company's own USB vendor and product IDs) and get it re-signed by
Windows Hardware Quality Labs (Winqual) under the "DUA" program. I did
this for our latest product family and it only required an expenditure
of 99 bucks for a Verisign Organizational Certificate (for signing
purposes) and some of my time to navigate the admittedly arcane DUA
submission process at Winqual.
