It is recommended to use a USB 3.0 port when connecting to the Portenta X8 which can deliver the required power.
Dynamic scaling of the Portenta X8 can change the current consumption, leading to current surges during bootup.
Average power consumption is provided in the above table for several reference scenarios.
