I have an LG Android phone. When I connect it to my Kubuntu box with a USB cable, it shows up, as it should, with lsusb. But the ID code is inconsistent: if I shut the Android off and restart it, the ID changes:

Bus 003 Device 029: ID 1004:61f9 LG Electronics, Inc.

and later

Bus 003 Device 031: ID 1004:61a6 LG Electronics, Inc.

That makes it impossible to make a consistent entry in /etc/udev/rules.d/99-android.rules.

What is going on here?

Totally normal behaviour. You should be able to write



  • The trouble is that I keep seeing IDs that I haven't seen before.

  • And the different IDs don't even have a common prefix.

It appears that using ATTRS{isProduct}=="*" will work no matter what the product ID is.
