I have an application trying to communicate to a serial port provided by a USB
to Serial Converter device (/dev/ttyUSB0).

The application fails to communicate and I think the following is where it

trace:comm:io_control 0x78 IOCTL_SERIAL_WAIT_ON_MASK (nil) 0 0x90e9f0 4
trace:comm:get_irq_info TIOCSERGETLSR err Invalid argument

The application states it fails to communicate even though I have blinking
lights on the device and can use picocom or screen to login.

$ picocom -b 115200 /dev/ttyUSB0

$ screen /dev/ttyUSB0 115200
