Hello,
If you still encounter errors like the one above even without the eMMC adapter installed in the box,
it looks like there is a hardware related problem.
To make sure, try activating the hardware test via Software.
Go to Setting menu -> General -> checklist on "Perform Hardware SelfTest at Startup", then close the settings window.
Restart the Ufi eMMC ToolBox Software, look in the Log window, then attach the screenshot here for further guidance.
