i want these files created with 666 just for the devil of it... ;-)


A better approach is to give access to a group, then add yourself to the
group. For example, I use the following code in a udev file
(/etc/udev/rules.d/60-cell.rules):

SUBSYSTEM!="usb_device", ACTION!="add", GOTO="cell_rules_end"
# LG Phone
SYSFS{idVendor}=="1004", SYSFS{idProduct}=="6000", GROUP="cellusers",
MODE="0660"
LABEL="cell_rules_end"

Of course, you'll need to find the idVendor and idProduct or other
identifying characteristics of the device (and change the names to make
them more appropriate).

Then, add yourself to the cell (or whatever) group.

what is the details of this group addition? this isnt the same group as
/etc/group is it?

i have created a file for my hiptop as ...
# pass all events to the hiptop access SUBSYSTEM!="usb_hiptop",
ACTION!="add", GOTO="hiptop_rules_end"
# Hiptop/sidekick

No, the first line should be (uncommented):

SUBSYSTEM!="usb_device", ACTION!="add", GOTO="hiptop_rules_end"

SYSFS{idVendor}=="0da0", SYSFS{idProduct}=="1002", GROUP="hiptopusers",
MODE="0666"

Use 0660.

and need next the where/how to create and join the group. tia, jackc...

$ groups jack

This is just to make sure you don't forget your groups if something goes
wrong.

# groupadd hiptopusers

Creates the group

# usermod -a -G hiptopusers jack

Adds jack to the hiptopusers group

Then, restart the computer.

Let me know how it goes.
