Question: What is multiple ReNumeration™? What is its use?
Response: ReNumeration™ is a cypress patented method by which the USB device can take on the identity of multiple USB devices by soft reconfiguration. Multiple ReNumeration™ - EZ-USB (AN21xx/FX/FX1/FX2/FX2LP) firmware can renumerate anytime. One use for this capability might be to 'fine tune' an isochronous endpoint's bandwidth requests by trying various descriptor values and renumerating.
