"When a Lightning cable is just lying somewhere connected to a charger/computer, but not connected to a device, HiFive limits current on the PWR to a really small value (around 10-15 mA according to my measurements). To enable full current, 0x74 request must be issued by Tristar and processed by HiFive." https://nyansatan.github.io/lightning/ https://nyansatan.github.io/lightning/
