The solution could be to build-in a more powerful one (a modification on a future version of the MCS) or by-pass it with an independent one that is more powerful.The current supplied by the MCS power supply is 3 Amps low for use with a direct attached SSD. As I said, I am using an independent power supply to bypass the problem. But this creates problems in shutting down the software and hardware correctly and safely, as the MCS does without an external power supply. All this is due to the need to have a short period of power supply from the USB during the shutdown phase.
5V 3amps is 15watts. It should be enough to power SSD and more.
I solved, with a suggestion from JamieFL, the problem of safe shutdown with self-powered SSDs and HUBs. By applying a diode on the +12 enable so as to have no return current. The MCS now does its job perfectly. Now I'm going to apply a Pimoroni fan with RPI temperature control.
Thank you all.
