I am developing a product for a small company. Product has USB interface for connectivity.
USB has 3 different configuration: HID keyboard, CDC and composite CDC plus HID keyboard.
As I understand I need 3 PID number and proper .inf file. Also .inf file should be signed.
Customer wants that Windows recognizes device and uses standard driver for HID and CDC automatically. Is it possible without .inf file? Customer doesn’t want to provide driver for their device.
What VID/PID number can we use, should we request PID sublicensing from STMicroelectronics?
