This is reserved for the Raspberry Pi 2.
With the default settings, the Raspberry Pi 2 limits the current to 600mA for all 4 USB ports. The software modification proposed here will extend this limit to 1200mA.
- This modification is not only for Recalbox.
- This modification is reversible.
- The use of a 2000mA power supply is always recommended, whatever the use of the Raspberry Pi 2.
- The maximum current allowed by the Raspberry Pi 2 is 2000mA.
If you need to connect, without using a self-powered USB hub, several power-hungry USB devices, without exceeding the maximum current of 1200mA on the 4 USB ports. For example: A 2.5" USB self-powered hard drive.
max_usb_current=...
.max_usb_current=1
or, if it already exists, change its value to 1.recalbox-user-config.txt
file.This tip also works on the Raspberry Pi 3, but the line
max_usb_current=...
does not exist in therecalbox-user-config.txt
file. You will have to add it manually.
