lsusb doesn't show that. I didn't know where to look for the dev files.

I've done that and here's the difference:

With your file:

$ ls -la /dev/bus/usb/004/003
crw-rw-r-- 1 root nut 189, 386 2006-11-02 18:50 /dev/bus/usb/004/003

With the original file before replug:

$ ls -la /dev/bus/usb/004/003
crw-rw-r-- 1 root root 189, 386 2006-11-02 18:55 /dev/bus/usb/004/003

With the original file after replug:

$ ls -la /dev/bus/usb/004/004
crw-rw---- 1 root nut 189, 387 2006-11-02 18:57 /dev/bus/usb/004/004

I guess /etc/hotplug/usb/libhidups isn't doing its job correctly on boot.
