I use external harddisk(connected via USB with its own power supply) to boot into dietpi on my raspberry pi. It works okay for a day(even with multiple reboots and poweroff). But the next day RPi sends no power to usb ports and so it doesn't boot.
When I use SD card to boot it works. Ethernet port works and I'm able to SSH. I've plugged my external drive using the USB adapter to another computer and I can confirm that it is working. I am using the official power supply (2.5A 5.1V).
If I try to boot after keeping the RPi off for more than 1 day from the external HDD it works again! But this repeats everytime. I can't understand this peculiar behaviour of my rpi 3b.
I have also set max_usb_current=1 in boot/config.txt but still no luck.
Here is the output of some of the commands I ran after booting with sd card on raspbian:

Please help me resolve this issue. Thanks :)
