[ Upstream commit 5d111f5190848d6fb1c414dc57797efea3526a2f ] wait_for_connected() wait till a port change status to USB_PORT_STAT_CONNECTION, but this is not possible if the port is unpowered. The loop will only exit at timeout. Such case take place if an over-current incident happen while system is in S3. Then during resume wait_for_connected() will wait 2s, which may be noticeable by the user.
