[SOLVED] FT230X Basic UART via USB Port

#1

Hi
trying to replace rpi3 with radxa zero sbc for logging power usage.
Using IR/optical coupler connected at usb port accessable by /dev/ttyUSB0 on OS.
Its working for rpi3 but not for radxa zero :frowning:

rpi3 detects FT230X Basic UART

usb 1-1.2: new full-speed USB device number 4 using dwc_otg
usb 1-1.2: New USB device found, idVendor=0403, idProduct=6015, bcdDevice=10.00
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.2: Product: FT230X Basic UART
usb 1-1.2: Manufacturer: FTDI
usbcore: registered new interface driver usbserial_generic
usbserial: USB Serial support registered for generic
usbcore: registered new interface driver ftdi_sio
usbserial: USB Serial support registered for FTDI USB Serial Device
ftdi_sio 1-1.2:1.0: FTDI USB Serial Device converter detected
usb 1-1.2: Detected FT-X
usb 1-1.2: FTDI USB Serial Device converter now attached to ttyUSB0

but on radxa zero
FT230X device connected to USB 2.0 OTG Port or USB 3.0 HOST Port
nothing/never appear.
I am struggle to track down this problem to hw or os or both.

Using radxa zero debian (buster) with 5.10.69-10-amlogic-g617a45dd0fce kernel

Can you try with some other USB devices to see if this affects other devices as well?

SOLVED.

Initial used existing usb-cable with a micro-to-usb-c adapter but this combo failed obviously.
Now using a cable with micro and usb-c plug.
Sorry for the noise.
