So, I have two power sources (two phone chargers, different brand, 5V-3.1A). Im using a raspberry pi 4B, and it's in boot from usb mode. The ssd connected to the pi is powered externally. If I power the pi and the ssd from the same power source, then it boots correctly. But if I power the pi from one of the chargers, and the ssd from another it doesnt boot. Note that both chargers are connected to a double connected to a wall oulet, so they both start at the same time, also trying to start first the ssd and then the pi, or first the pi and then the ssd gives the same results. I also tried two others 5V-1.2A, and 5V-1A chargers for the ssd, but the result was the same.
Here is the log:
