 * Devices listed here usually provide a CDC ACM port on which normal modem
 * AT commands and PPP can be used.  But when that port is in-use by PPP it
 * cannot be used simultaneously for status or signal strength.  Instead, the
 * ports here can be queried for that information using the Qualcomm DM
 * protocol.

/* NOTE: for now, only use this driver for devices that provide a CDC-ACM port

 * QCDM-capable ports.  Devices that do not provide a CDC-ACM port should
