Very hacky script for automatically bisecting kernel regressions on devices like the OnePlus 6

bisect-test.sh

#!/bin/bash

# basically what at-to_bootloader_hard does, turns off the USB port the phone is connected to so that
# VBUS is low and the device won't go to EDL (yay oneplus)
# then sends a byte to the arduino to tell it to perform a hard reboot by pressing volume up and power
# finally turn the usb port back on
# sudo uhubctl -a off -p 2 -n 2109:2812 && printf "%b" "\0x01" > /dev/ttyACM0 && sleep 15 && sudo uhubctl -a on -p 2 -n 2109:2812
