Even this is awkward.  It's silly to look up the endpoint in a table
when you already know that it is endpoint 0.  Just do:

        ep = &udev->ep0;

with no need to check for NULL.

After further checking, I realized that  usb_device udev is created by
ehset_single_step_set_feature and depends on usb_hcd and port. So I do
not get why the endpoint is at udev->ep0. Can you help me with this?
