There is good news for prospective buyers of the diminutive Raspberry Pi 4 as the USB-C issue that stopped the device working with some power supplies has been fixed.
The issue arose with the change to a USB Type-C connector for powering the device. An error in detection circuitry on the Pi side caused some power adapters to mistake the computer for an audio device, and therefore not shove the expected power down the line. The Raspberry Pi Foundation’s own USB power supply (yours for £8) was fine, other cables (marked with an “e”) were less so.
Pi fans have been speculating over the last few months that the fix had landed after purchasers reported spotting a new design in the wild.
