Hi!

Could I use the USB output to power up a USB hub? In the interface picture it says: 5V, current unlimited, but down in the user manual it says: USB2.0 type-A power output socket, which implies 5V 500mA, which would be not enough I guess.

The use case is that the RPI cuts the power on its usb 3.0 ports at shutdown too soon, causing an increase of the Unexpected Power Loss SMART counter. Using an active USB hub between the RPI and the USB SSD enclosure solves the problem, but at power loss the hub will be cut down as well, so it would be useless unless the UPS HAT powers it via USB power output. There is also a question whether the power of the USB hub has enough time after the RPI powered down. Somewhere I read that the HAT cuts power 3 seconds after the RPI shuts down, is it correct?

Thank you for the answers in advance!
