The hub driver matches based on the device or interface class, not the product ID. Changing the product ID won't hurt it. With the existing code, lsusb calls an xHCI root hub a "Linux Foundation 2.0 root hub", the same as an EHCI root hub. By contrast, UHCI and OHCI are reported as "Linux Foundation 1.1 root hub".
