On OMAP3, this only affects the USBTLL and USBHOST modules. There is probably a sleep and wakeup latency penalty with these enabled. No one seems to have quantified it yet. If the added latency is measurable, an alternate approach would be to only enable hardware save-and-restore if there are USB devices attached.
