Easy question....how many USB ports are on some of the newer
motherboards?
Six on the back....plus more on headers?

What about SATA ports, have they gone much beyond four?

This question has NOTHING to do with XP and is out of place HERE.

Ask elsewhere


How many USB ports does Win XP/Vista support? Not devices (127) but ports.
And, can I add 127 devices to each port within Win XP?


I assume your question is theoretical.

USB supports up to 127 peripheral devices which can be connected with USB
hubs to expand the number of connectors. The hubs can be connected more or
less in any configuration that you please, but the hub tree must be
dendritic* and there can be no more than 15 hubs between the host and any
peripheral.

*The A and B connector configuration forces this topology.
