Is there documentation of the settings in the Configuration.ini file used by the Sierra Wireless driver installer? I just installed the 4110 driver on Windows 8 x64 for my mc7355, and it did not install any of the COM ports. Then, I looked around on the net and redid the installation after setting USBCOMP=6 instead of USBCOMP=0 inside Configuration.ini. This resulted in the DM and NMEA com ports appearing in the device manager. I would like to have a reference of what each of the settings in Configuration.ini do. Is USBCOMP a bit mask? I have seen cases where it gets set to 14. What do these values mean? Thanks.
