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.

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
- Unplug it
Run udev monitor
Copy longest path, use it to get all needed info
