I then wrote a simple udev rule:

And ran udevadm control -R
to reload udev. When i now test with
udevadm test /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2:1.0/host0/target0:0:0/0:0:0:0/block/sda
My rule shows up, but when i plug in my device, nothing happens. Can someone help me out?
linux usb udev
My goal is to do different things, whenever a usb device is plugged in. I found out the kernel-path to my usb-stick when i plug it in which is
/devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2:1.0/host0/target0:0:0/0:0:0:0/block/sda
I can now run
udevadm info -a -p /devices/pci0000:00/0000:00:14.0/usb2/2-2/2-2:1.0/host0/target0:0:0/0:0:0:0/block/sda
which gives me
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
