First, apologies for the newbie question. Can someone point me to the policy concerning the use of mbed's USB Vendor ID in a commercial product? Also, which library file contains the VID and PID should I want to change them? Thanks in advance for any info!

Hi David,

Very nice to hear about a USB commercial product!

I am afraid that you cannot use the default VID/PID from the USB device stack for a commercial product. VID are owned by the vendor company and are assigned and maintained by USB-IF. Visit www.usb.org for more information on USB-IF membership and obtaining a VID. PID are assigned by each vendor as they see fit. Once you have a VID, you can assign any PID you like, as there will be no conflict amongst different vendor devices.

So once you have your VID/PID, you can use them just by changing them in the constructor of each USBdevice. For instance, let's say that you are using USBMouse:

USBMouse mouse(REL_MOUSE, your_VID, your_PID, your_product_release);

Out of curiosity, what are you building ?!

Hope that helps Sam

Sam, thanks for the info about VID/PID usage. I knew about www.usb.org and all, but was hoping to avoid having to spend $4000 on my own VID. Some chip companies (TI for sure and possibly Microchip as well) will let you use their VID if you register with them. I was hoping NXP/mbed also had such a policy but alas, apparently this is not so the case.

The device is a novel MIDI product - and top secret! ;)

Hi David,

We'll look in to it and see if there is any way we can help.

NXP has a program to get free PIDs under their VID:

http://www.lpcware.com/content/project/usb-vid-pid-program

But that is only available for the LPC11Uxx.

Has anyone thought about getting a PID from http://www.mcselec.com/index.php?page=shop.product_details&flypage=shop.flypage&product_id=92&option=com_phpshop&Itemid=1

Thanks to everyone who sent replies. The NXP program Igor indicated is exactly what I'm looking for! Paul, that MCS thing looks a little sketchy, and if NXP is willing to let me use their VID for free for three products, I figure I can reserve a little $$ from each unit to finance my own VID for the fourth product! Thanks again!

Best, DC

Hi David,

I was jsut googling for a few VID/PID related things, and found your original post, and also this.

Might be exactly what you're after?

Thanks, Chris

Hello, I received recently 3 Product Ids from nxp (usb-vip-pid program as mentioned above). Took a while (2 months) to get an answer, but this will let me start a small production until I make enough money to buy my own PID (5k$ now !) Thanks to NXP ! regards PP

Thank you for posting that Philippe. I've just applied and was wondering about the lead time.

Hello I m facing a similar problem, so I wanted to ask which Mbed you are using. Can I get VID/PID for mbed NXP LPC1768?

Thank you in advance, Debby
