I have compiled the HID example and noticed it does not work on any darwin system like IOS/MAC OS 10. Seems ok on Android and other PC's. What seem to occur is after 1 second the MCU stops. Strangely the USB still shows connected to the system. I have no access to root or the sudo password so I can not see dmseg output. I tried adjusting the stack and playing with a USB fake timeout/delays but nothing helps. Pending a USB sniffer or root privileges I'm out of ideas. Any one have a thought?
