how to connect LT26i(android ICS) to PC as android USB drivers ?

[#1]

i have an android app which can run in LT26i(qandroid 2.3.6), but it cann't run when update to android 4.0,  so i wan to debug this problem.

when i connect lt26i(android4.0) to pc, there is only portable device in window's device manager, there is not any android usb devices . and i  i can not update the driver to  usb driver. of course the debug mode in lt26i is opened.

so, what should i do to connect LT26i(android4.0) to pc as android usb drivers?

The Xperia S uses MTP mode for PC connection, you are aware of that, right? Have you checked your SI number in the thread to see if your phone can be updated yet?

Samuel, thank you very much!

I checked SI number, it is 1257-5188, that means my mobile can be updated from June25.

and I have updated my LT26i in about  July12 from  LT26i's update.

however, is MTP mode related with android usb driver?

[Samuel1]

I think so, yes.

There was a change in ICS which makes the phone only use MTP mode when connecting. I haven't found any work around for this yet unfortunately.
