The "$cdev" thing in devd.conf was *not* working. I don't remember if it contained the wrong value or if it was just empty. It did not work. Otherwise I wouldn't have to use a separate script at all. My wrapper script parses the output of usbconfig to get the correct device. That works reliably. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
