[SOLVED] hal not seeing usb

Hi folks, I've run into an issue that appears to be hal related (though I really have no idea, policykit, polkit, hal, etc, all confuse the hell out of me). Hal doesn't detect usb devices. I insert the device, and it's detected by the kernel, and a device node is created:

Insert:
# dmesg
usb 1-8: new high speed USB device using ehci_hcd and address 10
usb 1-8: configuration #1 chosen from 1 choice
scsi15 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 10
usb-storage: waiting for device to settle before scanning

HAL, however, doesn't see it:

[root@pinkwater kdm]# lshal -m

Start monitoring devicelist:
-------------------------------------------------
(plug, unplug, plug, unplug -- nothing)

I also verified that the number of devices seen by lshal doesn't change at all. Using KDE4.4 on a fully up to day system if that matters at all. What am I missing?

Looks like this was my fault. A while back I reinstalled udev because of some issues I was having with it, and had moved my old /etc/udev dir to a backup location. Apparently I needed a udev rule with the following in it:

# pass all events to the HAL daemon
RUN+="socket:@/org/freedesktop/hal/udev_event"

now things appear to be working. What's odd is this had *definitely* been working since then - I hadn't even upgraded to kde4.4 till a week or two after I messed with udev. My WAG would be that some change in policykid/polkit/polkit-1 requires this missing rule. I did verify that if I remove the rule, doing a forced reinstall of hal produces the rule, so that would have been the best solution.
