Hi, You are right, since it is now possible to use a PCI controller, we can use USB through it. This patch for completeness doesn't rely on PCI. Also, we have this patch for a long time, we just share it with the world, this kind of modifications could also be implemented in other models, like vexpress, if it's needed. Regards, Jérémy
