Dear David, I have a set of a host and device which I have paired using the cable association service and now the device tries to connect wirelessly. As soon as the DN_CONNECT from the device is received by the host bad things start happening until finally a crash is caused. Have you seen this type of problem below? any hints on what is going wrong?
