Subject: [PATCH] USB: option: Removing hardware ID disabling Novatel modems

Unfortunately some of the hardware PID belonging to auto-install CDROM (AICD) of Novatel modems found their way into the option module. This causes the AICD to be treated as a modem 
in stead of a disk. Since the modem ports do not appear until after the AICD is ejected, this essentially disables the modem. After a couple of minutes the AICD should auto-eject, but
it is just too long a wait. The frequency of the failure seems to depend on both the hardware and the linux distribution.

Below is a patch for the issue (also adding a couple of new PID, offering some explanations and removing some incomplete and unnecessary comments) against the latest stable kernel 
source (2.6.35.2). 

Please CC me on all issue related to this patch. 

Best regards,
