So just to be clear on the procedure.
- Unit plugged in working with the SDK no isses.
- Unplug the unit, /dev/ttyUSB and /dev/qcqmi interfaces disappear from the system.
- When the interfaces disappear you see what on your system? There are API’s designed to notify you of the loss of a device.
- Plug the unit back in, /dev/ttyUSB and /dev/qcqmi interfaces re enumerate back to the device numbers they previously had.
- At this point what are you seeing expecting the SDK to do?
