Thanks for the reply Oliver, No, nothing else connected on the other hub ports ( I use a 7 port Dlink usb hub) One more thing I want to say, here is a more detailed on the issue 1. on terminal 1 i run busybox microcom /dev/ttyUSB3 and issue the AT commands, and after i get connect OK from the other side, i keep the microcom window open. 2. Open a different terminal (terminal 2) and issue dhclient wwan0 or ifconfig wwan0 up with the above I see the issue in the above sequence, if I exit from the microcom window (terminal 1) and try the dhclient or ifconfig (terminal 2)i don't see any issue. rgds, GK -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
