You should be able to locate drivers for XP
Umm actually I doubt that it is that easy.
You do not "just" need usb3 drivers for Windows XP, you do need the drivers for the chipset that your virtual machine is emulating and while you can download drivers from anywhere I strongly advise against getting drivers from just a driver website if you like stability.
Personally I would only get a driver from either the chipset manufacturer, Microsoft or VMware.
VMware has not supplied a USB3 driver for Windows XP, that -at least- to me says something.
But I might be wrong, the driver might be out there, I have been known to be wrong before and will be happy to be proven wrong on this case once more
