I agree, the documentation is rather confusing and inaccurate. But also, having the USB sockets shared with the regular banana jack output really limits the ability to say supply a voltage for motors and run a USB-powered controller simultaneously. I wonder if there are any potential bugs in the implementation that could potentially cause a higher voltage to be applied to the USB ports (even if only transiently) which could be hazardous for connected equipment.

Good information, thank you. Being able to quickly access a USB power source is always handy, but this unit seems to have the added advantage of displaying the current being drawn.

This is good information for anyone using this device. Thanks for digging into the actual operation and contrasting it to the operation described in the manual.
