Getting free USB PIDs
Mitch Davis
There's been a bit of talk recently about AVR chips doing native USB.
Michael B told me that FTDI give out USB PIDs if you're using their
products. Well, I asked FTDI for some PIDs, and a few hours later, I
got back some mail with 8 PIDs for me to use. Nice!
Mitch.

Make sure you don't use them with anything other than an FTDI chip,
though - we wouldn't want to upset the nice company or far worse end
up with usb.org involved as they have been quite assertive lately in
controlling VID/PID pairs.

If only Atmel would do the same...

difficult for Sparkfun or similar companies. There were a few
companies that bought a VID and sold PIDs in small quantities a few
years back, but they got shut down by usb.org. There was some small
amount of discussion on various boards at the time about the
legalities involved, but the net effect was that these companies no
longer sell PIDs.
Atmel have provided PIDs in some particular circumstances, and I'm
sure it would be no problem if you were a volume customer (in which
case you would probably pay for a usb.org membership anyway and have
your own VID). I can understand why they don't provide them to just
anyone - there are so many hobbyists using Atmel micros that they're
probably afraid it would be too much of a burden. I still wish they
would, though.
If you do want to buy a VID/PID that can be used for anything it can
still be done - ask me at the meeting and I will explain.
