I am trying to install different OSes from an SD card but I keep getting "unknown eMMC" error.
It says it is 0 bytes.
It worked one out of 15 tries.
Is it a power supply issue?
It is 5V, 3A.

It sounds like the eMMC might be either corrupted or having intermittent connection issues. Have you tried a different SD card or reflashing the eMMC? Also, check your power supply and cable stability.

I think it had something to do with my USB hub and maybe power.

If the problem is related to the USB hub, how should I solve it?
