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.

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?

    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?

      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.

      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?

          IC on Digikey is 5x more expensive than board containing same IC on Alibaba: How? [on hold]

          .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 12 2 $begingroup$ I built a prototype using an NFC board I bought from Alibaba for 1$ (https://www.alibaba.com/showroom/rfid-rc522.html). It claims to use the NXP MFRC522 IC, and if I look on the board the chip has that part number and even the little NXP logo. It works like a charm on the prototype so now I'd like to build the NFC antenna into the product and use the same chip (I'll go through the antenna tuning/matching process). The problem is this: If I want to buy this IC on Digikey, it costs $5.36 for QTY 1 and $3.61 for QTY 1,500 (https://www.digikey.com/products/en/rf-if-and-rfid/rfid-rf-access-monitoring-ics/880?k=rc522).
