If you are using fedora, Changing permissions with the following (as root) will only remain accessable to other users as long as usb device is connected. If usb device is removed or pc reboots, all permissions are reset to root. chmod a=+xrw /dev/ttySO (if using serial) chmod a=+xrw /dev/ttyUSB0 (if using USB)
www.jpilot.org/pipermail/jpilot/2005-July/005210.html explains how to edit udev rules such that permission can be set for all users. vi /etc/udev/rules.d/50-udev.rules change KERNEL=="ttyS*", GROUP="uucp", MODE="0666" to KERNEL=="ttyS*", GROUP="uucp", MODE="0660" and the same for KERNEL=="ttyUSB*", GROUP="uucp", MODE="0666" NOTE: I dont know what security risks there are using these permissions. hope this helps, Cormac On Sat, 2006-08-26 at 12:49 +0800, Lau Ming Leong wrote: > How can I add myself to the uucp group?
