==Timeout Issues==
If you have comms problems like this you can add a custom timeout:
"USBDEVFS_CONTROL failed cmd blazer_usb rqt 33 rq 9 len 8 ret -110"
Add a new config item. The default is 2
config setprop nut pollInterval 4
Modify the template
mkdir -p /etc/e-smith/templates-custom/etc/ups/ups.conf
cp /etc/e-smith/templates/etc/ups/ups.conf/UPS /etc/e-smith/templates-custom/etc/ups/ups.conf/UPS
nano /etc/e-smith/templates-custom/etc/ups/ups.conf/UPS
Add the bits between the # comments
{
my $model = $nut{Model} || "usbhid-ups";
my $device = $nut{Device} || "/var/lib/ups/hiddev0";
my $type = $nut{Type};
my $mfr = $nut{mfr};
my $mdl = $nut{mdl};
# Add this
my $poll = $nut{pollInterval} || '2';
if ($poll ne '2') {
$OUT .= "pollinterval = $poll\n";
}
# ends here
$OUT .= "[UPS]\n";
$OUT .= "\tdriver = $model\n";
expand-template /etc/ups/ups.conf
cat /etc/ups/ups.conf
You should see something like this:
# Copyright (C) 1999-2006 Mitel Networks Corporation
#------------------------------------------------------------
pollinterval = 4
[UPS]
Restart nut
service nut restart
Now check to see the correct timeout:
upsc UPS | grep driver.parameter.pollinterval
driver.parameter.pollinterval: 4
To reset either delete the key, or set it to the default of 2
