sys/dev/usb ehci.c ohci.c usb_subr.c
Log:
When changing the device address and max packet size in usbd_new_device(),
close and re-open the default pipe instead of relying on the host
controller driver to notice the changes. Remove the unreliable code
that attempted to update these fields while the pipe was active.
This fixes a case where the hardware could cache and continue to
use the old address, resulting in a "getting first desc failed"
error.
