For USB offloading situations, the AFE port start command will result in a QMI handshake between the Q6DSP and the main processor. Depending on if the USB bus is suspended, this routine would require more time to complete, as resuming the USB bus has some overhead associated with it. Increase the timeout to 3s to allow for sufficient time for the USB QMI stream enable handshake to complete.
