<mark><span class="tb_blue">'''Important! Increases the USB current limit to 1.6A'''</span></mark>
By default, USB boot is not enabled with a 3A power supply or some third-party USB-PD capable power supply. If you are using a power supply that cannot provide 5A at +5V or not compatible, the current draw to USB peripherals will be restricted to 600mA and it might affect USB booting or cannot provide enough power to your hard drives and SSDs .
It is required that increases the USB current limit for peripherals to 1.6A by setting <span class="tb_blue">usb_max_current_enable=1</span> in the <span class="tb_blue">/boot/firmware/config.txt</span> file will override this and enable USB boot with a lower wattage power supply.
'''Open then Teminal window, then run the following command to open the /boot/firmware/config.txt file:'''
sudo nano /boot/firmware/config.txt
Add a line at the end of the file that reads like this:
usb_max_current_enable=1
[[File:X1100-setting1.jpg]]
Save and exit. In Nano editor, you do that by hitting CTRL + X, answering Y and hitting Enter when prompted.
Reboot the Raspberry Pi
sudo reboot
You can check the status of power output to the USB ports using ''vcgencmd''.
vcgencmd get_config usb_max_current_enable
[[File:X1100-setting2.jpg]]
This means that the USB current limit has been increased to 1.6A - Success!
