Hi mudrovc,

I apologize for the long time, but we are progressing to get this service soon,

By the way could you please let me know what is your STM32 production quantities per year ? and what is the end-product name :

1) string Product and

2) string vendor

You would like to have inside the USB descriptors..

Thanks for your comprehension,

STOne-32, :)

Hi pandoraems,

I didn't think this was the case hence this post:

In addition to what JJ said, besides being amateur-ish, AFAIK, it is downright illegal to sell USB devices without properly licensed PID/VID, even if the target customer is an enthusiast.

And usually, when people start to try to turn this hobby into business they have no idea of how many units they'd be selling

Thanks for your response pandoraems.

I had assumed ST had a unique VID/PID combination for things like the standard CDC driver. I take it this is not the case. If not then wouldn't it be sensible for ST to provide a PID/VID combination for standard drivers like the CDC driver that everyone using ST CDC driver could use? I assume there is no technical reason this could not be done.

Sorry if I'm restating what the thread is already about

:-?

Trevor, i am too lazy to reach for references now, but i am quite positive that it is the case as i've learned from my prior research.

Imagine a situation where you've paid your hard-earned cash for a set of PID/VID. Then someone comes to market with the same PID/VID that they've pulled out of a thin air (i.e made up and have not officially registered it)

If a user plugs both devices into his/her computer, the OS/drivers would be very confused as to how to handle the two devices with same PID/VID, and things will inevitably break.

Proper PID/VID licensing is designed to avoid these kinds of problems. (for an affordable price of $2000 or so ;) )
