usbtiny extra udev rule?

In the udev rules for usbtiny, there are 2 rules listed. Howver, adding the second one to my udev rules resulted in me not an "rc=-1" communication error when I tried to use my usbtiny. When I commented out this rule:

"SBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="0479", GROUP="users", MODE="0666"

everything worked fine. Not sure what the root of the issue is, but this rule makes the usbtiny programer unusable. -- Ssalenik (talk) 04:09, 6 March 2012‎

Extract the UDisks into new article

As UDev is more generic than just disk mounting subsystem, I propose to extract the UDisks part into its own page to keep things simple and clear. Lux (talk) 19:32, 27 July 2012 (UTC)

Agreed 100%. Sambul13 09.40, 03 September 2012 (UTC)

About udev rules

udevadm info -a -n [device name]

and

udevadm info -a -p $(udevadm info -q path -n [device name])

gives the same output but the latter is recommended by some Khampf (talk) 20:57, 5 February 2013 (UTC)

Use of 'uaccess' instead of GROUP and MODE?

Bug openobex - relies on non-existing group plugdev, conflict with systemd made me rethink the rules I have been using for Logitech_Unifying_Receiver.

Currently, the following rule is taught to the user:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="1781", ATTRS{idProduct}=="0c9f", GROUP="users", MODE="0666"

What about changing it to:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="1781", ATTRS{idProduct}=="0c9f", TAG+="uaccess"

As a developer note, Ubuntu versions before 13.04 Raring needs TAG+="udev-acl" instead of uaccess. For compatibility with modern and legacy systems:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="1781", ATTRS{idProduct}=="0c9f", TAG+="uaccess", TAG+="udev-acl"
