Keep blowing my Microchip MPLAB ICD-2 |

I am noticing that the ICD2 (from Microchip) gets blown easily, i've damaged 3 the past 5 months.
Somehow, the 9V dc adapter fails to power up the unit. In order to make it work now, I then have to go get my 12V from the USB port, and the 5V I have to plug my target unit's power on.
Is anyone else having a problem with blown ICD2s? |

Maybe its the MPLAB software setting.
Sounds like maybe your telling the software to try to power the test board throught the ICD. (which is the +5 usb volts or the +9V adapter voltage regulated to +5)
AND
also powering the test board it self.
It should be ONLY powered through the ICD
OR
ONLY powering the test board itself.
not both
BTW. if your getting +12 from a USB cable, THATS WRONG.
should be +5 from shield to pin1. |

I have 5 and have had no problems with any of them (been used quite a bit over the last couple years). |
