I want to use an USB device that has an internal Cypress chip for serial communication (9600 bps) to a radio module. The RPi does recognize the Cypress chip, but does not connect the device when I check available ttyUSB ports. When connecting a USB/TTL serial cable from another brand it connects.

I have a problem to connected my UPS to my USB port. This is information from my system.

Confirmed that it is this device by reconnect the cable

dmesg:

From /sys/devices/:

However, it doesn't show any /dev/ttyUSB*. I'm not sure what I have missing here.

Serial
  • Possibly it's created with another name. Check if there is any /dev node created by following instruction from How to allow software access to any USB devices?

  • Same as Jakob said in the comment, it seems that the new device is binded usbhid driver. You may check that using:

  • Another way to check all that using udevadm

    1. Unplug it
    2. Run udev monitor

    3. Copy longest path, use it to get all needed info
