Olivier, Thanks for helping. The locked semaphore was my problem. Easy now I know what I am looking for. I agree with you - it would be very nice if one of the developers could add a modem_run option to remove the semaphore and automatically remove it if loading the firmware fails.

So, if the first run fails, you won't be able to easily run modem_run again. Duncan posted a tip to remove the semaphore: get the id from /proc/sysvipc/sem, and try to remove it with ipcrm sem id. It would be nice to have a modem_run option to remove the semaphore, and to remove it if the firmware loading fails. Have you set the correct loader and firmware paths in speedtouch.conf ? If they're wrong, then modem_run will fail the first time and will be locked. You can add some debug options in the hotplug script (probably /etc/hotplug/usb/speedtouch) to see what happens, for example : exec /dev/tty1 (or exec /some-writable-file) set -x In Mandrakelinux, we got some other problems at boot because the usb controller triggers speedtch modules loading very early, and the hotplug script failed because it tried to set up a remover script, but /var was read-only at this point. If you fail to see what happens, then you can disable the hotplug script (move it away from /etc/hotplug/usb) and try to use modem_run once the system is booted.

I agree with you - it would be very nice if one of the developers could add a modem_run option to remove the semaphore and automatically remove it if loading the firmware fails. Regards Clive There are several problems in fact: - the semaphore has been designed to be kept in memory, that might be the first problem. - some errors in modem_run leaves the semaphore with an incorrect value, preventing modem_run to be run again. That's the second problem. Benoit PAPILLAULT Liste de diffusion modem ALCATEL SpeedTouch USB Pour se dsinscrire : mailto:[EMAIL PROTECTED]

Clive Messer [EMAIL PROTECTED] writes: Yes, the paths were/are correct. Have not changed them. Just removed the semaphore and 'speedtouch-start'. Need to check what happens when I reboot the box and the modem is detected by hotplug. Maybe your usbfs isn't mounted at this point. This happened in our Mandrakelinux package too. The usb controller is loaded very early, it triggers the speedtch module loading and the hotplug script, but /proc/bus/usb may not be available yet, then modem_run will fail and keep the line_ko value in the semaphore. You can do some pretty evil hack before speedtouch-start is run in the hotplug script, like this one : while [ ! -f /proc/bus/usb/devices ]; do sleep 2; done -- Olivier Blin Liste de diffusion modem ALCATEL SpeedTouch USB Pour se désinscrire : mailto:[EMAIL PROTECTED]

That's the second problem. Maybe modem_run could re-initialize the semaphore back to S_INIT if the firmware loading fails (or if any other error occurs). Then next modem_run instances will be able to try again. -- Olivier Blin Liste de diffusion modem ALCATEL SpeedTouch USB Pour se désinscrire : mailto:[EMAIL PROTECTED]
