All of which proves, that the iPad port, does not function as a USB
port. Which is the function i need.

what it proves is you don't understand what you're talking about. no
surprise there.

usb devices are either a host (i.e, a computer) or a peripheral (i.e, a
hard drive or printer). the ipad is a usb peripheral. it connects to a
usb host, such as your computer, both to charge and sync data.

it does not connect to other usb peripherals. that's why a usb cable
has different plugs at either end, because two usb peripherals can't
talk to each other. there has to be a host.

however, by using the camera connection kit, it is possible to plug
some usb peripherals into the ipad, making it function as a usb host.
that's for specific use cases, such as copying photos from a memory
card or for audio/midi support. it's not for generic usb host support,
which makes no sense for most devices.
