Hi Alan, Yes, I think it works as you expected. I have CONFIG_USB_SUSPEND and CONFIG_USB_DEBUG, and the behaviour is: If ehci-hcd is not loaded but only uhci-hcd, suspend and resume works just fine with and without USB devices plugged in. If ehci-hcd and uhci-hcd is loaded , suspend and resume works as expected if there is no USB device plugged at suspend/resume time, or if there are both uhci (USB 1/1.1) and ehci (USB 2) devices. If there are only uhci devices (USB 1/1.1) when suspending, they are not seen upon resume, unless I unplug/replug them again. Hmmm, interesting.
