udev dynamic linking?

I personally have tried the gentoo-wiki guide but it just doesn't produce the right links...and then I used the brief guide (http://linuxwacom.sourceforge.net/index.php/minihowto), but then, upon EVERY restart. /dev/input/wacom is not created, and there doesn't seem to be a way to create this.

So I would like to know if ANYONE has gotten this to work--and what methods they used.

This is the only error I can really find

Not sure if this is what you're looking for, but it works:
/etc/udev/rules.d/10-local.rules:
# set ownership, permissions and aliases for scanner, tablet, mobile phone
BUS=="scsi", ID=="0:0:2:0",                             SYMLINK+="scanner", GROUP="users"
BUS=="input", SYSFS{name}=="Wacom Intuos2 6x8",         SYMLINK+="tablet", MODE="0644"
...

Which creates:
Code:
~ $ ll /dev/tablet
lrwxrwxrwx 1 root root 12 2007-02-07 19:09 /dev/tablet -> input/event3

You'd need to change the tablet name unless you have the same model, or choose a different matching criterion.

I point the X device definitions to /dev/tablet, no worries. (I'm not sure why I have the MODE setting there, it doesn't do squat for a symlink....)

Ok, I'll try this, except without the scanner part I guess?

One problem, however, is that ll is not a real command and when I try ls -l, it says there is no such directory as /dev/tablet.

My problem with the guide is that it never creates wacom_udev, like it's supposed to...

I don't know why udev doesn't work right; it's not really important anymore...so the problem isn't solved; I just went to do it statically.

Heh, sorry about that, ll is an alias for ls -l. It's such a common one I forgot that it's not actually universal. :oops: If you want it, add alias ll="ls -l" to ~/.bashrc.

If you decide to revisit this, double-check the udev rules to make sure you have "==" and "=" in the right places. The two are not interchangeable and the wiki's example using only single-equals will no longer work. Also try different sysfs matching parameters, I recall that some attributes didn't work reliably for me either.
