Raspberry pi zero and USB3 memory stick

Raspberry pi Zero (Pi-Zero) may not be able to recognize USB3 devices because of a power shortage of USB port. My Extreme Pro USB3.0 stick (128G, SANDISK) is not recognized by Pi-Zero without using a self-powered USB hub. However, a self-powered USB hub is too inconvenience to carry due to a bulky AC adapter.

The "max_usb_current=1" in the /boot/config.txt, which changes the Maximum USB current to 1.2 A, is not effective for Pi-Zero

I am using "Double-Powered USB hub (USB-HUB227WH3, SANWA supply, JAPAN)" which I bought very long ago.

If the Red connector is connected to a USB port or a power adapter, electrical power of USB hub is overloaded above 1A, like a self-powered Hub.  It can also be used as a bus-powered hub without using the Red connector.

With the USB-OTG setting, My USB3.0 memory stick can be used in Pi-Zero by connecting the red connecter to a 1A power adapter only.

Needless to say, just USB2.0 speed.
