HAL and hotplugging

[Dustin Spicuzza]

Ok, so I've stumbled through the process of trying to get input 
hotplugging work in conjunction with HAL, and so I thought that I had a 
good idea of how its supposed to work... except that apparently my idea 
is wrong.

I created an FDI file:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <match key="udi" 
contains="usb_device_eef_1_noserial_if0_logicaldev_input">
      <merge key="input.x11_driver" type="string">evtouch</merge>
    </match>
  </device>
</deviceinfo>

and placed it in /etc/hal/fdi/information (and tried /etc/hal/fdi/policy 
). Which, after restarting X and HAL a number of times, did nothing. 
strace says that HAL read the file, and I'm assuming that it did 
*something*, but the key doesn't show up in hal-device output... which I 
assumed it was going to.

Interestingly, I added -logverbose 10 to the xorg command line, and 
while I saw lots of other things, I didn't see any HAL or DBUS related 
messages (despite their presence in config/hal.c). Is there a sure fire 
way to figure out whether that stuff is actually doing anything?

Also, on another thought, how does one tell the driver what options to 
set? I was looking in config/hal.c and I didn't see anything that 
allowed that.

Thanks for any assistance you can provide.

Dustin
