I am having an intermittent problem with a TWR-S12G128 board. Sometimes it works fine. With nothing changing, Code Warrior suddenly cannot communicated with it. If I try to unplug the USB and reattach it, I frequently get an error message of “USB Device Not Recognized, One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.” I have had this problem on multiple computers. Help?
If you are using the OSBDM please try to change the USB cable and if this doesn't help then the section of the board that is responsible for the OSBDM programming is experiencing a failure.
In such cases we recommend to use PEmicro programmer either the USB Multilink or Universal Multilink connected to proper BDM headers on the board.
I hope this will help.
