It's easy to get upset with udev. On rawhide, the wacom rules simply don't work. The problem is that now there's no decent way to get Vendor/Product ids when you receive an eventX creation event. This is needed so the wacom rules can create /dev/input/wacom-tablets/<model> link. The current ugly way to fix it is to use ATTR{../id/vendor}. There must be a better solution. Yes, the rule worked for some time (BUS=="usb", KERNEL=="event*", SYSFS{idVendor}==...)
