Description John Griffiths 2013-09-23 19:25:23 UTC

Description of problem:
When an USB serial device is used, apcupsd fails to start at system boot even though it is enabled.

Version-Release number of selected component (if applicable):
apcupsd-3.14.10-10.fc19.x86_64

How reproducible:
always

Steps to Reproduce:
1. install a USB serial device
2. configure apcupsd to use the USB serial device, (DEVICE /dev/ttyUSB0)
3. reboot the system

Actual results:
apcupsd does not start because it cannot connect to the serial device.

Expected results:
apcupsd should start

Additional info:
Using systemctl start apcupsd.service after the system has booted starts apcupsd successfully.

Do you have ModemManager installed?
If you do, try to remove it, reboot and check if apcupsd works or not.
If you need ModemManager, install it back. If you are connected via modem, download ModemManager rpm first (using yumdownloader) so you don't need internet connection to install it back.

Also what is the apcupsd error message exactly?

Comment 2 John Griffiths 2013-09-24 15:20:11 UTC

Yes, I had ModemManager installed. No, did not need it. Removed it and apcupsd started correctly.

Thanks.

Comment 3 Michal Hlavinka 2013-09-24 15:39:24 UTC

Unfortunately, ModemManager steals all (usb)serial devices during boot.
