MPLAB X IDE will not connect to ICD 4
I might be missing something but I am having this same problem and have not seen any clear solutions. I just recently began using the ICD 4 and it was a little flaky at first and then seemed to settle in. Have seen flakiness in previous microchip programmer/debuggers so giving it a kick seemed not unusual. Now I can't communicate with it at all. It would sometimes and sometimes not show the serial number of the ICD 4, which appears to say it has communicated with the device. The blue LEDs are constantly on. I am using the usb cable that came with the ICD 4. I am using MPLAB X IDE v5.05 running on Windows 10 Home version. Have updated it to the most recent revision.
The Microchip web page for the ICD4 doesn't offer any solutions. It does have a document about Uninstalling Incorrect USB Device Drivers. Its from 2011 and the drivers it refers to as incorrect are not not the current drivers windows uses.
I have tried connecting to various USB ports, reinstalling drivers, closing MPLAB and restarting, powering down and restarting both the ICD 4 and computer. Can't run the self test because it can't connect.
The ICD 4 manual has some troubleshooting tips but can't do anything if MPLAB does not see the device. It has a section for invoking the bootload mode. Does not work because MPLAB it does not see the ICD 4 in bootload mode (purple LEDs). The next section 4.4.3 comes with dire warnings. EMERGENCY BOOT FIRMWARE RECOVERY UTILITY FOR for use in rare situations, use only if it does not work on any other machine. I will try other machines first.
I have seen other posts but none with any clear solutions, just lucky anecdotal solutions. If I find a solution I will post it so that others don't have to go through the hours I have spent on this.
Any help on this would be greatly appreciated.
