serial device other than /dev/ttyACMx, v1.6.9

Development Tools IDE 1.x

i have recently moved from linux version 1.0.x to 1.6.9 and at the same time to slackware 14.1. 14.1 includes the kernel module cdc_acm, which at this point i'm assuming is how boards are given the /dev/ttyACMx device. i'm not really concerned that the boards are assigned a ttyACMx as the assignment does work with the boards.

however, i have some different boards with different firmware and have defined udev rules for each. the names vary, but are along the lines of /dev/ttyUSB8 or /dev/ttyS22. those rule sets continue to work by building the symlinks, but 1.6.9 will not list them.

so the question -- how do i get this version of arduino to list tty devices in addition to the ACMx?

thanks in advance.

This helped me. Adding your user to the dialout group usually does the trick.

it seems that with this version of linux, all i can set with udev is a symbolic link.

/dev#ls -l uno
lrwxrwxrwx 1 root root 15 Apr 17 21:46 uno -> bus/usb/001/010

symlinks are always readable by everyone and owned by root, but the access is set on the reference file.

/dev/bus/usb/001# ls -l
total 0
crw-rw-rw- 1 root dialout 189, 9 Apr 17 21:46 010

all this is to say that it looks like the arduino code does not recognize symbolic links. can anyone verify this?
is there any way to get the arduino to use a symlink for a device?
