When using a USB device that implements the CDC communication protocol with Linux, the device is recognizable and Linux will be able to receive data from it with any modification. It is not a modem. Cdcacm 7-1:1.0: ttyACM0: USB ACM device If detected correctly, the USB device should be connected as a ttyACM.
USB communications device class (or USB CDC class) is a composite Universal Serial Busdevice class.
The communications device class is used for computer networking devices akin to a network card, providing an interface for transmitting Ethernet or ATM frames onto some physical media. It is also used for modems, ISDN, fax machines, and telephony applications for performing regular voice calls.
Microsoft Windows versions prior to Windows Vista do not work with the networking parts of the USB CDC, instead using Microsoft's own derivative named Microsoft RNDIS, a serialized version of the Microsoft NDIS (Network Driver Interface Specification). With a vendor-supplied INF file, Windows Vista works with USB CDC and USB WMCDC devices.[1]
This class can be used for industrial equipment such as CNC machinery to allow upgrading from older RS-232 serial controllers and robotics, since they can keep software compatibility. The device attaches to an RS-232 communications line and the operating system on the USB side makes the USB device appear as a traditional RS-232 port. Chip manufacturers such as Prolific Technology, FTDI, Microchip, and Atmel provide facilities for developing USB RS-232 devices.
Devices of this class are also implemented in embedded systems such as mobile phones so that a phone may be used as a modem, fax or network port. The data interfaces are generally used to perform bulk data transfer.

Installation Requirements
CDC driver version 2.15.3000 provides functionality on Windows XP but will prompt with a warning message as Microsoft no longer certifies drivers for use on the Windows XP operating system.
For Windows 10 Users -The Windows 10 native CDC driver included in the Windows 10 operating system supports Zebra scanners and should be used to provide CDC functionality in the Windows 10 environment.
Install the software package according the Release Notes provided.
