USB Hub killed my raspberry pi?

Sat Aug 04, 2018 7:51 pm

I've been using my raspberry pi zero in conjunction with a USB hub and wifi adapter for 4 months now. This particular hub requires external power from a 5v adapter. I knew that it was giving back power into the RPI for a while. I used the RPI with octoprint to great success. Today, I went to check up on my printer and it had stopped. I rebooted the whole machine and the RPI didn't turn on. I went through 2 hours of troubleshooting and I believe my RPI is dead. Is it possible that the USB hub could have killed my RPI? Both are powered by a 5v 2a dual port usb adapter.

Maybe the problem is related to the micro SD card (for example, corrupt data due to an uncontrolled shutdown).

I recommend to repair the two partitions ( vfat boot and ext4 root) of the SD card. You will need a Linux system (PC, Live DVD, virtual machine, RPi, etc) for such procedure.

If you have more SD cards, try installing a new raspbian on your RPi. If this new install works, your RPi is not damaged.

Its a possibility, but more likely you destroyed one of the power supplies.
Can you switch them?
