Here are the changes that I have here to allow controlling devices through the external script.

Rebased on top of current master branch.
@andersson any hope to hear response from you?

The last patch fixes the external support or fixes in all cases ? If it fixes all cases it should got in a separate or right ?

It is a generic fix, but I stumbled upon it only with the "external" driver, since other drivers do not output a lot.

Is it possible to combine this with the qcomlt debug board? For the phones I have a Pi Pico exposing a compatible serial control interface, but for USB VBUS I need to use PPPS control...

@calebccff here is (an excerpt) of the script that I have here for the relays and PPPS hub:

#!/bin/sh

#set -x
set -e

if [ "$#" != 3 ]
then
	echo "Usage: $0 [board] [command] [on/off]"
	exit 1
fi

echo "Called $1 $2 $3"

case "$1" in 
	"rb5-2" )
		HUBLOC="10-1"
		HUBPORT="1"
		LAURENT="REL,1"
		;;
	"db820c-1" )
		HUBLOC="10-1"
		HUBPORT="2"
		LAURENT="REL,2"
		;;
	"rb1-1" )
		HUBLOC="10-1"
		HUBPORT="3"
		LAURENT="REL,3"
		;;

	* )
		echo "Unknown board $1"
		exit 2
esac

uhubctl() {
	sudo uhubctl -l $HUBLOC -p $HUBPORT -a $1
	if [ "$1" = "off" ] ; then
		sudo udevadm trigger --action=remove /sys/bus/usb/devices/${HUBLOC}.${HUBPORT}/ || true
	fi
}

laurent() {
	curl "http://laurent.lan/cmd.cgi?psw=$LAURENTPW&cmd=$LAURENT,$1"
}

#echo "$2-$3" >> /tmp/cdba-log

case "$2-$3" in
	"power-off" )
		uhubctl off
		#sleep 1
		laurent 0
		#sleep 1
		;;
	"power-on" )
		uhubctl off
		#sleep 1
		laurent 0
		#sleep 1
		laurent 1
		;;
	"usb-on" )
		uhubctl on
		;;
	"usb-off" )
		uhubctl off
		sleep 1
		;;
	"key-power-on" | "key-power-off" )
		# ignore
		;;
	*)
		echo "Unknown command $2-$3"
		exit 2
		;;
esac

I hooked up my pico to control the enable pin of the buck converter I have as a battery replacement, this makes all the button wrangling unecessary as I can just erase the boot partition and the devices always boot straight to fastboot mode.

There is maybe some value in this PR for someone else, but given the amount of finesse necessary to get this to work reliably, I'm not gonna stick with it... See #33

Edit: oops, I meant to leave this comment on #21
