// copyrighted by Tacx and is not distributed with Golden Cheetah.
// Instead we ask the user to tell us where it can be found when they
// configure the device. (On Windows platforms the firmware is installed
// by the standard Tacx software as c:\windows\system32\FortiusSWPID1942Renum.hex).
//
// So when we open a Fortius device we need to search for an unitialised
// handlebar controller 3651:e6be and upload the firmware using the EzUsb
// functions. Once that has completed the controller will represent itself
// as 3651:1942.
//
// Firmware will need to be reloaded if the device is disconnected or the
// USB controller is reset after sleep/resume.
//
// The EZUSB code is found in EzUsb.c, which is essentially the code used
// in the 'fxload' command on Linux, some minor changes have been made to the
// standard code wrt to logging errors.
//
// The only function we use is:
// int ezusb_load_ram (usb_dev_handle *device, const char *path, int fx2, int stage)
// device is a usb device handle
// path is the filename of the firmware file
// fx2 is non-zero to indicate an fx2 device (we pass 0, since the Fortius is fx)
// stage is to control two stage loading, we load in a single stage
