2.1.5 Port Power Options: Port Enable and Port Disable Select
Any downstream facing port on the EVB-USB5744 can be disabled if desired. When
both DP & DM signals are pulled up to +3.3V, by default the USB5744 automatically
disables the port, reports the corrected number of available ports to the host, and drives
the PRT_CTRL line for the disabled port(s) low.
To enable a port, use its Port Enable switch to select the “EN.” position. The associated
“Enabled” LED will light.
To disable a port, slide its Port Enable switch to the “Dis.” position. The “Enabled” LED
will extinguish.
