Hi: i am doing the job of porting the zephy kernel to arm9 based socs, which embeded XHCI usb controller, i reviewed the device drivers in ./zephyr/driver/usb and did not found the EHCI moudle drver, even the "*HCI" symbol not found. so i want to know if i miss something? if not supported hci really, why? thanks for your kindly support.

We presently have only USB device (and not USB host) support in Zephyr, that’s why you are unable to find host controller drivers under Zephyr/drivers/usb
> if not supported hci really, why? USB device side was the logical place to start for resource constrained devices targeted by Zephyr. (Going forward It is possible that USB Host / OTG functionality can get added based on community interest / demand / contributions.)
