This patch (as1070) creates a new subroutine to check whether a device can be resumed. This code is needed even when CONFIG_USB_SUSPEND isn't set, because devices do suspend themselves when the root hub (and hence the entire bus) is suspended, and power sessions can get lost during a system sleep even without individual port suspends. The patch also fixes a loose end in USB-Persist reset-resume handling. When a low- or full-speed device is attached to an EHCI's companion controller, the port handoff during resume will cause the companion port's connect-status-change feature to be set. If that flag isn't cleared, the port-reset code will think it indicates that the device has been unplugged and the reset-resume will fail.
