Anyone having trouble with their PICkit 4 enumerating in Windows?

Windows 10, tried on three machines, a dozen different ports (direct, powered hub, USB 2.0. USB 3.0 etc), the only way I can get it to properly enumerate and be recognised by MPLAB X 4.15 after removing it following a programming or debug session is to go through the Hardware Boot Emergency Boot Firmware Recovery procedure in the Debug menu.
 
I should add that PICkit 3, ICD 3, Real ICE and ICD 4 all enumerate and work as expected with MPLAB X 4.15 on these machines.

Hi I figured out the PICkit 4 problem. When you inserted the supplied cable Micro B end, it was shorting the D- pin on the receptacle to ground. There was no short when no cable is inserted. I fixed it by removing the USB receptacle, placing some carefully cut Kapton tape over about 1/3 of the five SMD lands closest to the board edge, and replaced the receptacle. I don't know if this is just my unit, or if others suffered. When it worked, it turns out that either I was using a different cable, or it was just pushed in slightly differently.

Dang!
Great fault finding!

This forum is mis-configured so it only works correctly if you access it via https protocol.
The Microchip website links to it using http protocol. Will they ever catch on?

Howard,
 
It's not just your unit.
 
Received mine about 2 months ago and decided to use it for the first time today. Would not enumerate. 
 
Tried the emergency recovery and it just made it worse.
 
Same problem with the pins shorting with a cable plugged in. Was going to send the unit back but couldn't find my invoice.
 
Anyway pulled off the connector and stuck the kapton tape to the underneath of the connector before soldering it back on. Problem solved. 
 
The supplied cable is a very tight fit. Using a few of my phone cables the fit is very loose and wiggling the cable drops the device from Windows.
