Bug#628750: udev: takes too long to detect and configure mouse (steelseries XAI)

Package: udev
Version: 169-1
Severity: normal

Udev is taking around 15 secs to detect and configure my mouse. If you take a
look at my bootchart, you see a big hole: http://i.imgur.com/whbA8.png . That
hole is caused by udev trying to figure out my Steelseries XAI mouse. This (
http://imgur.com/7tSVP.png ) is the same bootchart with the mouse unplugged.
You can see that when I plug it, a modprobe runs and takes about 15 seconds. I
don't see any weird module loaded for the mouse afterwards (hid, usbhid and
that's it), so the modprobe is pointless (?).

Here's the dmesg output (at loglevel 9) after booting my PC without the mouse
and pluggin it in:

Why would there be a 5 sec delay between detecting the device and loading it as
a mouse? And then another delay on detecting the hidden devices?

For comparison, this is a fresh boot, pluggin in a logitech mouse:

It's almost instantaneous...

On that same boot, I unplugged that mouse, and plugged the XAI. Again, 5 secs
delay between the plugin and input doing something.
