Then what was before? Indeed they do not look like anything
reasonable... old VID do not appear on any of Odroid boards.

The first is acutally an Intel hub, the second is a webcam. Where did
I found them? I can't be sure today.

In case of USB devices the kernel uses topology information to match
devices instead of compatible properties and u-boot uses
aliases. Therefore, bad IDs don't break anything.

Ahh, and one more thing - these are two separate issues to fix, so two
patches.
