This device is not a serial port, but a virtual CD-ROM device. For
example with my Novatel MC950D:

lsusb -v -d 1410:5010 | grep InterfaceClass
      bInterfaceClass         8 Mass Storage

After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:

% lsusb -v -d 1410:4400 | grep InterfaceClass
      bInterfaceClass       255 Vendor Specific Class
      bInterfaceClass       255 Vendor Specific Class

Variable name says that 0x5010 is a Novatel U727, but searching in
internet shows, that this device also provides virtual CD that should be
ejected before use. Product id for serial port in this case is 0x4100.
