So, what is needed to make it work also on arm?
Is this done just through the io file, declared for x86 (legacy),
so that Linux handles usb? I mean, there is no need for drivers on
L4 side? Since Linux has them...?

I'm asking this, because I didn't find any specific pkg in L4 for USB.

So now, by declaring the usb interface in the io file, L4Linux obtains physical
access to it (or better, is allowed to access those addresses).
Please correct me if I am wrong.

By "platform specific part", do you mean to enable the omap USB driver in Linux
kernel configs? And maybe include libusb + usbutils (for lsusb)?

Thanks for your help and of course your patience :D
