idVendor and idProduct on usb.id

[A. Andria]

Hi,

As you should know, i'm a novice in linux. I'm using Ubuntu 5.10 (kernel 
2.6.12).
I've nokia 3120 and DKU-5 Cable. I can find usb.id file.

Should i download and recompile kernel source or only add the Vendor and 
Product Id to the usb.id file ?
Is still my DKU-5 need pl2303 module or not to make it work with gnokii ?

This is the Detail from lsusb -v -s 003
