The tool for loading firmware expects an USB serial port to work on.
When the module is in firmware loading mode, it would become
Bus 001 Device 010: ID 058b:0041 Infineon Technologies
After adding this ID to usb-serial-simple, tions, Driver=, 480M usb_serial_ simple, 480M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 480M
|__ Port 4: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M
|__ Port 1: Dev 10, If 0, Class=Communica
|__ Port 1: Dev 10, If 1, Class=CDC Data, Driver=
And a /dev/ttyUSBn would be created.
