    no node is created in /dev in raspbian stretch lite

    faM_4540176

      Hi, i own a light engine which uses cypress dual channel module. the problem is, when i plug it to my RPi, the node is not created in /dev directory. so i can not communicate with the port.

      the device is listed when i run "lsusb" as bellow:

      pi@raspberrypi:~ $ lsusb

      Bus 001 Device 006: ID 04b4:000a Cypress Semiconductor Corp.

      Bus 001 Device 004: ID 0424:7800 Standard Microsystems Corp.

      Bus 001 Device 003: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub

      Bus 001 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub

      Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

       

      and here is "dmesg" result:

      it just mounted in: /dev/bus/usb/001 and not mapped to /dev

       

      i installed the CyUSBSerial_SDK_Linux and modified the 90-cyusb.rules but nothing happened.

      anybody can help me?
