Some Questions to Answer First

  1. 1.Which device are you working with? 
Often an upgrade to a newer version of MPLAB X IDE is required to support newer devices.
  2. 2.Are you using a Microchip demo board or one of your own design? And, have you followed the guidelines for resistors/capacitors for communications connections? 
 See Operation.
  3. 3.Have you powered the target? 
The debugger cannot power the target if greater than 50 mA. For applications needing more than 50 mA, use an external power supply to power the target board.
  4. 4.Are you using a USB hub in your setup? Is it powered? 
If you continue to have problems, try using the debugger without the hub (plugged directly into the computer).
  5. 5.Are you using the USB cable shipped with the debugger? Other USB cables may be of poor quality, too long or do not support USB Communication.
