Hi, when the usb.agent is called by /sbin/hotplug with some parameters (e.g. ACTION, INTERFACE, DEVICE, PRODUCT, TYPE), I miss the assignment between these specific device variables and the attached device file name string "/dev/bus/ttyUSBx". Is there an environment variable, which contains this device file name string or from where I can get it?
Looking forward to hearing from you again. Kind regards Wolfgang Zodel -----Ursprüngliche Nachricht----- Von: Greg KH [mailto:[EMAIL PROTECTED] Gesendet: Montag, 19.

For 2.6 you will get a hotplug event when the ttyUSBx device is created. Use that event to determine what device it is connected to. For 2.4, look in the /proc/tty/drivers/usbserial file.
