Josh, the usb_modeswitch maintainer, is also maintaining this Android app: http://www.draisberghof.de/android/pppwidget.html That's one possible solution. According to him, there is also "a number of Chinese Android tablets (from the A10 family) that are supporting a number of 3G modem sticks by providing usb_modeswitch on-board, which is obviously working well." That's another possible solution. Userspace mode switching on Android should not be any more difficult than userspace mode switching on any other Linux distro. You unbind the usb-storage driver and submit your bulk message. Looking at a sample Android device (Galaxy S3 running the default image): shell@android:/ $ cat /proc/version Linux version 3.0.31-836582 (se.infra@SEP-97) (gcc version 4.4.3 (GCC) ) #1 SMP PREEMPT Tue Jan 15 14:17:21 KST 2013 shell@android:/ $ ls -l /dev/bus/usb/001/ crw-rw---- root usb 189, 0 2013-02-19 19:51 001 crw-rw---- root usb 189, 2 2013-03-07 09:01 003 it looks like your app will need to be a member of the "usb" group to do this. I assume there is a way for an app to request such permissions in Android. Josh has obviously managed to get it.
