Vanvalkinburgh.org How to get past the hanging in blanflash

If you don’t want to hold the button constantly, there’s another way, run the below.

echo 0 > /sys/bus/usb/devices/1-6/authorized
echo 1 > /sys/bus/usb/devices/1-6/authorized

To get the path, use the below.

for X in /sys/bus/usb/devices/*; do 
    echo "$X"
    cat "$X/idVendor" 2>/dev/null 
    cat "$X/idProduct" 2>/dev/null
    echo
done

All stolen from here.

Holding the power button, might restart it or something, so it’ll never work. Probably has to run all commands, without it rebooting. And replugging the cable would be easier.

while true; do
        echo 0 > /sys/bus/usb/devices/1-6/authorized
        echo 1 > /sys/bus/usb/devices/1-6/authorized
        sleep 30
done

Is thirty seconds of sleeping long enough? Or to long? Might be to long, at least I don’t have to mash the keyboard every time it stops now. I can easily run the blankflash 200+ times, until it magically works.

You could make a script to automate the entire thing, I’d use Python, check how long the output stays the same, if longer then 10 seconds, reset USB.
