Background - The USB 'enumeration' process seems to indicate that there is no method to manually pre-configure an ID/address into a single specific USB device,
but instead there is a scanned list of connected USB devices which are not in a guaranteed order/sequence
(which can be assigned an index position ID from the list which can be used for device access).
Question - So how can we automate a process (use program code) to directly access the same single specific USB device after PC reboots,
when there are 2 Cypress USB devices connected simultaneously to a given PC?
