I have discoverd that i have a huawei e160 (Medion Mobile S4011 Web Stick) instead of an e220/e270.

In Windows it shows up as huawei 3G and in the driver diagnostic tab the stick answers it is an e160.

It seems there is no new firmware from medion for this stick and flashing with firmware of another provider ends with a question for the right password. The last try i made is to disable the pin in the connectionmanager from Medion, because the manager ask me for the puk1 AND the pin. I think linux asks for the correct pin too many times and after this the huawei ask for the puk, too!

Fortunately this works with the main-kernel (2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux)!!!!

Disabling the pin seems to be a workaraound for users with an e160 huawei web stick. Can someone confirm this? Perhaps it is a problem with the pin / puk management ? I have tried so often and i am very sure it was the right pin which i'm used.
