Thanks & Regards,

Is "USB Serial Converter support" enabled in kernel menu?

See attached Clipboard02.jpg file.

Find configuration for your device in kernel menu for your device. See attached Clipboard04.jpg file.

Have a great day,
Pavel Chubakov

Are you sure about this /dev/ttyUSB0? Maybe you got some other device entry also.
