Inspiron 5551 I cannot boot LINUX

On my Inspiron 5551 I cannot boot LINUX
from an external SSD. The system was installed
using the "live" version.

The problem is that the BIOS (UEFI) cannot find the
disk with the system connected to the USB 3.0 port (left side of the computer).
If I connect the drive to USB 2.0(right side) then the drive is visible as both
UEFI and LEGACY.

I have also noticed this property that:
-when I connect for example a memory card with RescueDisk 
(or any other system with a UEFI partition) to the
USB 3.0 through a HAMA reader with USB 3.0
the BIOS does not detect this card.
However, if I connect the SAME card via a
USB 2.0 reader, BIOS sees the card.

My conclusion is that there is a problem with the USB 3.0 port.
Of course when I enable "Security boot" then the disk is visible 
but I cannot boot system from this disk.
