Raspberry Pi USB Cypress (CY8CKIT-049-42xx) conect…

Hi,

i want to receive data on Raspberry Pi via UART from Cypress. Here’s what I did. I connect RPi to power supply, then:

• pluged keyboard and mouse to RPi,
• run lsusb on terminal – I saw a mouse and keyboard detected,
• run ls /dev/tty* – I saw a list of UART devices (including keyboard and mouse),
• pluged cypress to RPi (via USB),
• run lsusb on terminal – I saw a mouse, keyboard and cypress detected,
• run ls /dev/tty* – nothing changed to the previous log (do not detect the cypress).

What can be wrong? Maybe I need to change some config file or sth else?
