hi

NUT 2.4.3 on new server can not see serial number, but old nut on different hardware can?

I have 2 USB-hid ups from APC, 1500 and 3000 RM, i use the serial number to identify them. However my new UPS monitor server can not see the serial number?

It works on 
	Linux dkserver 2.6.22.18-vs2.2.0.6 #1 SMP Sat Feb 16 20:54:32 CET 2008 i686 GNU/Linux 
	debian package 2.2.2-6.5

it does not work on
	Linux dkplugbab9 2.6.32-00007-g56678ec #1 PREEMPT Mon Feb 8 03:49:55 PST 2010 armv5tel GNU/Linux 
	NUT 2.4.3 self compiled

But if i use
	udevadm info --name=/dev/bus/usb/001/011 --attribute-walk 
i can see it just fine?

    ATTRS{product}=="Smart-UPS 1500 FW:653.12.I USB FW:4.2"

What is going on here?
