Hello Oliver,

I've been reading the USB CDC specification, but i have to admit, its
all rather dry material.

I'm feeling a little lost developing on both sides of the puzzle. Can
you provide me with a kind of lsusb printout of what the usb device is
supposed to look like?

what I've got right now is a CDC virtual com example, figured i could
modify it.
