Need USB config example /etc/nut/ups.conf

[MikeLieberman]

I know what USB port the USP USB cable is run to on my computer, but for the life of me I am unclear how to rewrite the config file to point to the USB port.
The command to write the basic file before the change to USB would look like;

Code: Select all

cat >> /etc/nut/ups.conf << EOF
[ups]

        driver = blazer_ser
        port = /dev/ttyS0
        desc = "my server1 ups"
EOF

I know the UPS is on port 3:
Bus 001 Device 003: ID 04b4:5500 Cypress Semiconductor Corp. HID->COM RS232 Adapter

And
ls /dev/bus/usb
001 002 003 004

But /dev/bus/usb/003 is a directory and not valid.

How is the port line written?

I tried:
[ups]

driver = blazer_ser
port = /dev/bus/usb/001/003
desc = "my server1 ups"
EOF

But then I checked to see if this worked:
# /lib/nut/blazer_ser -a ups
Network UPS Tools - Megatec/Q1 protocol serial driver 1.57 (2.7.4)
tcgetattr(/dev/bus/usb/001/003): Inappropriate ioctl for device

Here is the port info:

What am I doing wrong?
