    Hello,

    Just to confirm, you are having issues with USB-TO-GPIO adapter and noticing this behavior while downloading is that right?  Can you confirm what version of the adapter you have?

    If you have downloaded Fusion Studio there are some additional tools that are included - specifically: USB Adapter Firmware Download

    If you open this tool it will tell you the current firmware on the adapter.  Upgrade your adapter to 1.0.14 and see if the issues continue.

    Hi

        

    1, the same computer, programming procedures, long programming time

    For example, the following primary programming UCD3138, the original 10.224 seconds, the new 17.91 seconds. If it is secondary programming UCD3138-064/128, the gap is even larger. (Impact on efficiency)，

    2.

    Recently, the newly bought adapter is very easy to crash, programming more than ten or twenty devices began to crash once, restart the software and normal programming.

    Often in the following item on the software automatically quit or error, error report see the attachment.

    3.Compared with the adapters purchased on the website for a long time, there are two different versions. Please check the differences marked on the PCB board. Will this affect the use of the product?

    4.The failure rate of adapters is high, 3 adapters were damaged during programming today, and there were some damaged before, please inform us of the solution

    5.The product has been upgraded, but the problem is still not solved

    Johnsin, I have never heard of adapters being destroyed.  I suspect there may be some kind of voltage difference or excess between the target board and the PC, and this is causing the boards to be damaged.  Have you looked at the ground difference between the PC and the target board?

    Is the target board being powered by the adapter board or by something else?

    Are the pull up resistors on the target board tied to 3.3 volts?
