I loathe the 'feature' of udev that forces you to create or modify
/etc/udev/rules.d/51-android to let your cheap'n'cheerful unlisted
Android Device get through udev security. And now it seems that vdev is
about to force the same thing. I know it isn't easy to completely
re-think how things should be done, do OSX and the BSDs have a different
and better way of doing this sort of thing?

I want to ask you why a database of $V/$P/$N mappings is needed. It is
my laptop and my cheap Android tablet and I want to plug it into the USB
socket and have them play nicely together. God knows what I would have
done if I was just a normal ordinary person. I would have concluded that
linux was shit and gone back to my Mac or Windoze.

dmesg knew all about my android tablet when I plugged it in, why can't
vdev pick it up from there?

this is what I had to add into 51-android having had a look at dmesg first.

#    my cheap Android tablet
