Do you hear the USB "beep" sound when you connect/disconnect FlashScan?
Check that FlashScan's USB name is still intact: Use the program \Program Files (x86)\EFILive\Drivers\Utilities\usbview.exe
You should see an entry named exactly "EFILive FlashScan V2" shown in the image below.
If you do not see that entry, check the USB cable between FlashScan and the PC. Sometimes the PC's USB system can't/won't supply enough power to FlashScan. Try connecting FlashScan to a vehicle and your PC at the same time. That way the vehicle's 12V system will be powering FlashScan. It may be enough to get it working so that you can reprogram the firmware.
If you do see that entry, and the values highlighted in red match what you see, then start the EFILive Control Panel, click on the small FlashScan icon in the system tray near the clock to expand the EFILive Control Panel window.
Select the [F8: Trace] tab page and ensure that the "Enable Diagnostic Tracing" option is checked.
Select the [F2: USB] tab page, click on [Status].
Select the [F8: Trace] tab page again and click [Save Trace].
Locate the saved trace file and either attach it to this thread or email it to me directly.
