I know sometime the problem is really EMI because I can reset some modems (even powered modem) but not all by switching the light off in the room where the computer is. But it may have sometime a part in software like in previous eci driver. Maybe the problem is usb-uhci driver related? Every time I saw this message, it was usb-uhci related. I ggole a bit to verify if it was true Google give only 38 hits with 'already running port 1 disabled by hub (EMI usb- ohci' and 190 hits with usb-uhci. This one with usb-ohci and speedtouch usb may be with old software http://forum.hardware.fr/hardwarefr/OSAlternatifs/sujet-18184-1.htm In the case of the speedtouch usb, because of the bus address change, modem_run end and now we are in a state where nothing but resetting the usb is possible. The firware is still inside the modem so modem_run can't load it again. Unloading speedtch and usb-controller modules and loading again and then the modem is able to restart. I wrote a script wich when ppp-ipdown is run act as a watchdog and reconfigure the modem if necessary. It does have the advantage to work with every ADSL modem even those like the speedtouch usb and eci-usb wich need a specific program to be run before to be able to reconnect.
