udev rule does not fully work for TIM551 #17

Hey,

I could not get proper permissions on the TIM551 (kept having to do chmod 666 /usb/002/003)

until I modified your included udev rule to:

SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="19a2", ATTR{idProduct}=="5001", GROUP="plugdev", MODE="666"

I guess you are not in the plugdev group.

ibaranov-cp commented 10 years ago

Would it not be easier to add the mode 666 so that regardless it works for everyone? On 22 Sep 2014 16:52, "Jochen Sprickerhof" notifications@github.com wrote:

Feel free to do so, but I would not recommend it for everyone, as it's a security problem. Maybe we should add a hint to the documentation about the plugdev group. Feel free to send a patch.

ibaranov-cp commented 10 years ago

Forgive the ignorance on my part, but how is 666 on a USB port a security problem? (For my own knowledge :)

jspricke commented 10 years ago

It means everyone on the PC (might be remote) can access the port (i.e. write to it).
