[Nut-upsuser] how do I find the association between a usb port and a /dev entry?

[Steve Kelem]

I looked through the faq, but couldn't find an answer to this.

I'm trying to configure nut-2.0.4-26 on SuSE linux 10.2.

In ups.conf, I have

[myups]
    driver = belkinunv
    port = /dev/undefined
    desc = "Local UPS"

I'm trying to find out what the port should be set to.

lsusb shows:
