[MTCB Software Development] m4f1050:
I have a feeling serial USB driver, PPPd or something is missing in the kernel.

serial USB driver is required for PPP Widget v.1 to work.

EDIT: Here is a logcat of entries containing "ppp" and another one of entries containing "tun" maybe someone can pinpoint where the issue is at?
