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 section Operation.
Have you powered the target? An external power supply must be
connected to the target (preferred) or the debugger.
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 standard communication cable (RJ-11 type) shipped
with the debugger? If you have made a longer cable, it could cause
communications errors.
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.
