USB Power

USB power controls the external USB host-port power rails (when the device firmware exposes GPIO rail control).

What This Page Controls

• Whether rail control is available on this unit (the device must report GPIO mapping).
• USB-A state: enable/disable USB-A rail power.
• USB-C state: enable/disable USB-C rail power (host port rail, if present on this unit).
• Active high enable toggles: advanced polarity controls that must match the device firmware wiring.

Notes:

• If the device reports no GPIO mapping for rails, the UI disables the on/off controls.
• This page controls the power rails for the host USB ports. It does not change USB gadget mode on the USB-C device-mode port.
