Huawei EM700 SIM card recognition

Hello, we currently test a Huawei EM770W modem in a customer application together with ofono and connman. Dialup works fine so far with the 2.6.35~rc5 kernel from Meego 1.1 developement trunk. With kernel 2.6.33.3 from Meego 1.0 we had the problem that the communication got stuck from time to time. We had to reload the option.ko kernel module then. We use the recent release versions (0.26 and 0.55). The problem is that a SIM card is only recognised, when inserted before the device is powered on. A restart of ofonod is not a solution either. Is there a way to reset the modem through ofono that it will recognize a recently inserted SIM card? Regards Florian Mayer Mayer Electronics
