I can see you have a USB device with a yellow exclamation mark under other devices.
Does this USB device disappear if you disconnect your mitras?
If it disappear than it is your Mitras and you have to install the driver under "C:\Program Files (x86)\GHLControlCenter_V1054\Tools\FUJITSU USB DIRECT Programmer\driver\Win7" manual.
After the installation restart your computer and try the firmware update again.
