After upgrading libusbx from 1.0.15 to 1.0.16 I noticed that one of my scripts
broke because the output of lsusb (from usbutils 007) got changed.
I bisected it to commit 6853291 which added hotplug support to the Linux
backend. For now I am using `sort` to get some of devices sorted by bus number,
originally I blamed a new kernel version, so some more details are available on
http://www.spinics.net/lists/linux-input/msg26954.html. (FWIW, `lsusb -t`'s
output does not change in 1.0.16)
