I'm newbie at USB, if someone can help it would be wonderful:
I'm envisioning a gadget that would take input from a USB port on a PC
(or any USB host). And it would act as a UPS for four downstream USB
devices, providing currents upto 1A.
In other words, the gadget would have 4 USB sockets for output, capable
of providing upto 1A to devices connected to it.
I have done some reading on USB but would like to ascertain whether the
gadget needs to have a controller / or can it be a passive device, as
far as the USB interface circuitry is concerned ?
(of course, the gadget would have its own separate supply, from where
it will derive the UPS power)
