That last sentence is your first mistake. You should use either the
serial cable or the USB cable, not both. Connect it to one computer,
then set the other one up as a slave to the first one. I suggest the
USB. It is less troublesome than the serial even with apcupsd.
Let's get the USB host working, then we'll work on the others.
Once you connect it, you should see something like:
root@issola:~# lsusb | grep Power
Bus 001 Device 003: ID 051d:0002 American Power Conversion Uninterruptible
Power Supply
root@issola:~#
For host b, the USB host, you have:
> UPSNAME LG27a
> UPSCABLE usb
> UPSTYPE usb
> DEVICE
I have DEVICE comment out. I don't know if that will make a difference
or not.

Everything else look good. You should see:

If the daemon is running, you should see the web server at

Does anybody read signatures any more?
