So it should be called before connection will be setted up. Look for other embedded projects. For ex., in wive-ng there is a script that is called from mdev by line:
1-.*:1.* 0:0 0000 @/etc/scripts/usbctrl.sh and script is here: https://gitorious.org/wive-rtnl-ralink-rt305x-routers-firmware/wive-rtnl-ralink-rt305x-routers-firmware/blobs/master/user/usb/usbctrl.sh ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ------------------------------------------------------------------------ leaf-user mailing list: leaf-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-user Support Request -- http://leaf-project.org/
