Sorry - by error I did not send the message to all. Hi everyone, and good Sunday! The problem is that - between those two firmwares things might change, and so we don't know what Windows does when it meets this specific branch /version of the firmware. I am desperately suspecting that we would not get anything hinting a lot even looking at the usb capture of this specific firmware, but... in any case it might be interesting to have it. (at+gmr returns the firmware revision) Is the dongles with 23 firmwares working under Linux? Or, you might upgrade all dongles firmware until all of then are running the 23 version and so workaround the problem differently in case. Bjorn: I noticed that anyway, as Alex suggested, tcpdump can reveal some traffic: in particular you can see the gateway asking for us ... but no traffic can flow out, only flow in. The system can see traffic coming in, not generate it. Any idea or comment from anyone is welcome. -- 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
