Hi Sebastian,
Hi Andy,
It seems pretty nice to handle them through the kernel target framework.
I'm not too familiar with usb gadgets -- my initial take is that it
wouldn't make sense to enable this on a desktop machine, because
desktops can only be hosts, due to USB design? But I wanted to double
check there wasn't a corner case where we might also want it there.
You need an USB Device Controler (aka UDC) in your machine to be able
to run a gadget. Desktop machine don't have such a thing. There are
some PCI cards but usually those are eval cards.
There is dummy_hcd in kernel which is an emulator. It provides host &
device interface for testing purpose. This is the only thing you can use
without real hardware.
Thanks -- Regards -- Andy
Sebastian
