ESP-WROVER-KIT 4.1 Power Supply and General Question

[ats3788]

Hello ESP32 Espressif friends
I fiddle with my new ESP-WROVER-KIT 4.1.
I like it and I didn't had a Problem without WiFi.
With WiFi I need the 5V Power Supply but when I change the Jumper
the UART Port is not working. What does I have to do, to make it work
with the Com Port and Power Supply. Can I put another Jumper
next to the USB Jumper.
I miss this in the Documentation or I missed it.

My Power Supply has only 70mA is that to low ????

Anyway when I plug the USB cable into the USB Port I get two COM Ports COM5 and COM6
COM6 is the Port I do the Serial stuff What for is COM5.

70mA is way too low. The ESP32 needs at least a 500mA power supply.

Thank you that is what I thought.
What a pain in the ass, I'm on vacation and have to use this stupid Power Supply
