Power for USB Midi Controllers

I’m curious as to the amount of power that the USB port provides for external midi controllers. How does the power supplied by the USB port affect the power requirements of the Meta Module. Is the power for the USB port pulled from the 5V rail? I’m considering several different options for where I will mount the Meta Module (including the potentially a 4ms Pod) hence my question on power requirements. Thanks.
