Vaša iskustva sa dobivanjem USB VID/PID i ST USB driver za Win

[prasimix]

Postavljam ovom pod ARM, budući me zanima za STM32 platformu, ali je pitanje generalno: ima li tko iskustva sa dobivanjem USB VID/PID? Do sada nisam imao taj problem jer sam se skivao iza Arduino Due. No, ako ću koristiti USB port od STM32 MCU, onda pretpostavljam da više ne smijem izvan razvojne faze koristiti njegove ID-ove. Što je u tom slučaju sa USB driverom za Windows-e? Treba li pisati vlastiti?
Za VID USB-IF traži 5000 USD, ili učlanjenje od 4000 USD/godišnje. Postoje i "inicijative" za open source projekte poput pid.codes i openmoko.org za koje neki misle da neće doći pod udar advokata USB-IFa jer su to sve sitni projekti iza kojih stoje sitne ribe.

Evo primjer iz Nizozemske gdje izgleda da su USB-IFovi advokati bili u akciji:

When you develop your own USB product you probably do not want to pay 2000$ for a Vendor ID.
Why would you need a VID ? Each USB product requires an unique VID and PID number.
Since the VID is a WORD(2 bytes) there are many possible numbers.

Each of your unique products need a unique PID. This is also a WORD(2 bytes).

Another option is to buy a PID from MCS. Together with the VID you will have a unique combination.
MCS has sold PID's since 2005.
When MCS purchased the VID, there was NO INFORMATION about the usage of the VID-PID.
USB-IF was only focused to get a payment. There were no rules or conditions or a contract.

That changed in June 2009 when USB-ORG wrote an email that it was not permitted to sell VID or PID.
MCS pointed out that in The Netherlands you can not enforce or change rules AFTER a product/service is sold.
So we continued as usual.
In reaction USB-ORG offered our money back but that would mean existing customers would not have a valid PID anymore.
So we got some more letters and finally USB-ORG wrote a letter that they revoked our VID.

Of course our VID can not be re-used by USB-ORG. This means that our VID will still be unique.

If you want to produce a USB device that need to be tested/verified by USB-ORG you need your own VID.
If you only need a real unique VID & PID combination, you can still use ours.
So what we offer is a unique VID & PID combination.

Dakle, jedna mogućnost je kupiti od njih PID za 15€ što je puno bolje od nekadašnjih 2000 USD ili današnjih 5000 USD. Pisao sam i ST-u da vidim može li se od njih dobiti PID (pod njihovim VID-om).

Ja sam dosta davno (2007. okvirno) dobio od Microchip-a njihov VID i meni određeni PID, tako da su mi izašli u susret. To je bilo besplatno.
Kako je sa ST-om, nažalost, nemam informacija.

Dobio sam službeni odgovor od ST podrške:

it is indeed possible to get USB PID code from ST for your product but since this is for open source product, getting code from pid.codes service is probably going to be easier and faster. Pid.codes provides free USB PID codes specifically for open source projects.

Please note that pid.codes is not affiliated with ST.

Dakle, spremni su dati PID, bez detalja je li to nešto košta, ali za open source i sami predlažu pid.codes koji sam već spomenuo.
