Is USB working on L4Linux/L4Android?
Yes, on x86.
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.
I defined USB in my io file as following (for beagleboard):
USB => new Device() { .hid = "usb"; new-res Mmio(0x48064000 .. 0x48064fff); new-res Irq(77); }
Can L4Linux access now to the USB interface, or are any further steps
required?
That's one thing, and then make the platform specific parts work in L4Linux.

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 Giorgio
