Host controllers have hotplugged forever. The simplest way to see this in action is to build a host controller driver (maybe "ohci-hcd" if you have OHCI hardware) as a module, and then use rmmod/modprobe. You'll see the HCD's bus appear/modprobe or else disappear/rmmod, and USB devices will enumerate. If you have a hotpluggable host controller and bus (Cardbus/PCI was the original platform) you can try that too. Same process, except you'd also be doing electrical hotplugging not just the driver module dance. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
