None of the recent kernels can resume-from-ram reliably for me if I use CONFIG_USB_SUSPEND (set). But with that option UNset, suspend/resume to/from RAM works very well. BUT.. new in 2.6.14-rc*, is that the ehci_hcd USB hispeed driver no longer survives resume from ram. I have to unload/reload the module to get hispeed USB after resume. -ml
