Right, this is a bit of a mess:

- udev and through that libinput and others only use hwdb

- lsusb and lspci in ptxdist currently install their own .ids files.
  Latest upstream versions don't contain the .ids file any more but support
  both hwdb and the .ids file.

- usbip only supports the .ids file and in ptxdist looks in the wrong
  location :-/

- lshw only supports the .ids files and installs it's own versions of it
  :-/

I would prefer to use hwdb for everything (there is a reason why it was
introduced in the first place) but that's clearly not yet possible.

So I think for now the best would be:

- create a hwdata package with suboptions for usb and pci.
- in usbutils.in:

	select HWDATA		if !SYSTEMD_HWDB
	select HWDATA_USB	if !SYSTEMD_HWDB

If you use /usr/share/hwdata to install the files, then usbip will be fixed
automatically. Make sure that lsusb find the file as well.

Bonus points for updating lshw to use the same files :-)
