K3770 USB init result toggeling

Hello,

I got some times different device states after power on the UMTS K3770 like this:

'Found device in serial mode' (see first log below) what is OK and I can run the application

or

'Found device in CDFS mode' (see second log below) what is not OK.

How can be forced to find the device in serial mode only (vid:12d1 pid:14c9) instead of 'found device in CDFS mode' (vid:12d1 pid:14d1)?

Comments are welcome! thx/Klaus
