All xHCI host controllers are supposed to conform with the xHCI specification, and the Linux xHCI driver is written to that spec. So the code should work on any 0.96 xHCI host controllers. (Support for hosts that conform to the 1.0 xHCI specification is not in Linux yet, but AFAIK there are no 1.0 xHCI host controllers on the market.) I know that uPD720200-based hosts work, and I suspect that TUSB7340-based hosts also work, although I haven't had a chance to test them. Please let me know if you run into problems.
