If you’re a maker, hobbyist, or startup company producing your own USB device, you’ve probably discovered that you need a USB Vendor ID and Product ID to uniquely identify your device to computers. The USB-IF’s position is that the only way to do this is for each organisation to pay $6000 for a unique Vendor ID, which they may not share with other individuals or organisations.
For many makers and small companies, this is a prohibitive amount of money, and forces them to resort to workarounds, such as using other organisations’ VIDs without permission, or simply making up a VID and PID. These solutions make things worse for everyone, by damaging the assumption that a VID/PID combination is unique to a given device.
pid.codes seeks to solve this issue for anyone producing open-source hardware. We have been gifted a Vendor ID by a company that was issued one by USB-IF and has since ceased trading; they obtained the Vendor ID before the USB-IF changed their licensing terms to prohibit transfers or subassignments.
pid.codes will assign PIDs on any VID we own to any open-source hardware project needing one.
We have been granted a PID code for the AXIOM Remote:
This now needs to be integrated into our AXIOM Remote firmware in the USBCDCDevice-Class by altering the Descriptor.
idVendor and idProduct
