You can also set up modes and have different commands on the same throttle buttons and hats.

You can use the throttle from the X52 without its stick and use the Xtreme 3d together.

I've used my ST90 with my X52 throttle without the joystick plugged into it.

Ended up with x52 throttle and xtreme 3d stick, old computer died and the new dont have enough usb ports for pedals so im back to twisting and so far it works surprisingly well. A plus is that throttle on the 3d stick now can be used for rpm.

Powered USB hub will let you use your pedals and ease your stick grip.

As FLS said, a powered USB hub is what you'd need. If all of your USB ports are in use, they may easily run out of power, causing all kinds of less pleasant things. Another plus is that by using a replaceable hub the USB ports of your computer won't wear out.
