What box are you using?
On PCs power on by USB or CIR usually has to be enabled in the BIOS.
On AML boxes this is would be handled by u-boot, the vendor u-boot version might be tied to the remote that came with the box, not sure if power on by USB is supported. Not really my area
Good friend I'm using KI Pro mecool!
We did not need the usb, the controller picked up right without accessories
Well, thank you for clarifying.
