Has the USB Host bug issue resolved it? Is there any insights into why it happens (usb devices appear and disappear during subsequent reboots?).
Is it related to Edison module or breakout board ICs????
No, the latest release is 3.0 and it can be found in https://software.intel.com/en-us/iot/hardware/edison/downloads https://software.intel.com/en-us/iot/hardware/edison/downloads. Let me know if you continue to see this behavior in the latest image.
