I use Kinetis USB stack and I implemented 3 interfaces for my USB device. The last interface is usb_device_cdc_acm.c USB serial device. My USB device uses custom VID and PID (not NXP's or Freescale's).
On Windows 10, I can select Microsoft's driver for usb_device_cdc_acm interface in Device manager and usb_device_cdc_acm interface install as COM port. However, what driver can I use in my situation for Windows 7?
Thank you for you advice.
