Hello,I have Mecool Ki pro and ssd usb 3.0 box. When I try to boot from a usb hub dont work.Connected to direct KI usb if it works.
Have you tried all ports and is the SSD seen as a device when connected to the hub whilst booting CE directly from a USB port?
I just tried another usb ugreen hub 3.0 and if it works for me, start coreelec from the ssd.
