In you application the USB-Serial Device is configured to vendor SPI/I2C class (PID 00A), only the devices configured as CDC class (eg UART CDC mode) which are bound to Linux CDC ACM driver will create a node under /dev/ttyACM and you can communicate with it using applications such as minicom (similar to teraterm in windows). Refer to Testing a USB-Serial Bridge Controller Configured as USB-UART with Linux® – KBA92551 .
Can you please let me know how you want to communicate with the device? You can use the TestUtility.c application as well.
You can install the CyUSBSerial_SDK_Linux from https://www.cypress.com/documentation/software-and-drivers/usb-serial-software-development-kit and run the Test utility.
Please refer to the README.txt file in the path : installation directory-> CyUSBSerial_SDK_Linux -> linux -> testUtility on how to use the testUtility.
