When attached to a Linux host, the USB-CDC-ACM connection will automatically be configured,
assuming the Linux host is configured for USB host operation and the "cdc_acm" driver is
available. Once recognized, the cdc_acm driver will configure a standard serial port in the /dev/
ttyACMx series, where x is a number 0, 1, 2, 3, etc.
Caution:
Under Linux, if the /dev/ttyACMx device is in use when the PremierWave
EN unit is rebooted, some terminal programs under Linux will
automatically disconnect while others will not. If a terminal program
does not disconnect automatically, when the PremierWave EN device
comes back up, the CDC-ACM connection will be enumerated to a
different /dev/ttyACMx device.
