Thanks. This looks as nice as we can possibly do for now. I am happy to add Reviewed-by: Bjørn Mork <bj...@mork.no> This patch also helped me understanding the problem you face even better: It's not the "set_altsetting 0" that's causing problems, but the "set_altsetting X" prior to that. And that is certainly not something that a firmware should expect. I will look at the Huawei modem again when I get some time and see if there is any way we can possibly avoid it. Bjørn
