but this would only solve the problem for scratch, and not for other activities and legacy programs that want to use USB serial. you're suggesting that every activity that might need access to a serial port be modifide? (frankly, the restriction on device access to specific groups only makes sense when those devices are "important" in some way. since the user is free to unplug and discard this device, i hardly think it matters if they use it as intended.) paul =--------------------- paul fox, [EMAIL PROTECTED] _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
