The USB ports on my Raspberry Pi 2 model B V1.1 do not receive any power. I measured the USB pins with a multi-meter, which should have 5V, but have none.

  • I tried different power supplies, which work properly on another RPi 2.
  • I measured C97, C98, C99 and C100, all of which receive no power.
  • The Pi boots properly, the GPIO pins do have 5V on them.
  • The USB peripherals work fine on other devices.
  • I tried different SD cards with different Linux distros.

I tried looking for any polyfuses for the USB ports, but I cannot find them for the RPi 2.

Looks like hardware is damaged for some reason?

Also, have a look at these links:

Disabling USB ports

Apparently, there are commands to turn off USB power as mentioned in these threads. Maybe you could try some to enable the USB power.
