Hi, I'm working on Debian bug #244978, which asks if usbutils is needed for anything, or will hotplug suffice. In /etc/hotplug/hotplug.functions, there is a note: " usbmodules used for (a) multi-interface devices, (b) coldplug" Do you know if usbutils is needed for multi-interface devices, or will hotplug suffice?
