Which device are you working with? Often an upgrade to a newer
version of MPLAB X
IDE is required to support newer
devices.
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.
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.
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).
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.
