This README contains information regarding the USB device drivers needed for communication with Locosto based devices. csstusb.inf & csstusb.sys These two files install the USB device driver used for reprogramming the Locosto chipset. This is only necessary if the USB_BOOT pin of the Locosto is tied high. Immediately following power on, the Locosto attempts to connect to the reprogramming tool, CSST, for the first 4-5 seconds. Enabler_IIIG.inf & PhSerUsb.sys These two files install the USB device driver used to create one or more virtual COM ports. These COM ports will attempt to enumerate immediately if USB_BOOT is low, or after 5 seconds if USB_BOOT is high. In general, this 'drivers' directory can be used for both installations. Microsoft is smart enough to search through the .inf files looking for the proper VID and PID.
