but,ubuntu can not drive this ic,

driver=none,normally,it should driver=ftdi_sio,i test this ic in my host pc ,show picture below.

when i test another ftdi ic,like ft232,NX can drive it normally.

and,/dev/ will creat a ttyusb0 device,so ,i do not know if NX ubuntu can not drive a new ftdi chips,so i need a hand to solve this problem ,thanks.

Hi,
Do you use Jetpack 4.6.4 or 5.1.2? And beside adding the device in command line, is it required to enable additional configs?

We have guidance for customizing kernel image and certain configs is not enabled by default. Probably some configs have to be enabled for using the device.
