[Bug 1539348] [NEW] udevadm info reports wrong ID_MODEL_ID and ID_VENDOR_ID for USB serial port
Public bug reported:
Running udevadm info with the device path of a virtual serial port
created by a USB device (in this case a Particle Photon development
board) returns the ID_MODEL_ID and ID_VENDOR_ID for the USB host
controller instead of the Particle device.
The consequence is mis-detection of the device associated with a virtual
serial port in applications.
udevadm info with the virtual serial port. Expect ID_MODEL_ID=c00a and
ID_VENDOR_ID=2b04
