Hi Holger
To give you an update. As far as I can tell, the changes I have submitted, with the addition of a change (on my local system) where the USB protocol has been modified to remove USB overrun, is stable so I can monitor iPhone 5S as well as Galaxy S4 continuously. If anyone asks, I would be happy to send them the USB protocol changes. However, it will be INCOMPATIBLE with earlier firmware based SIMTrace boards.
I am making changes to the host program (on Windows) to monitor multiple SIMTrace devices, and am interested to know if anyone else is working on something similar.
Best Regards
