PBP3.1 Gold + MCSX+ + Microchip's ICD3 programmer?

[richard]

Most of the time, there is even no communication with the ICD3.

Something with Endpoint ..etc.

All start with the new MPLABX thing. When I used the MPLAB 8.xx it worked OK.

After changing firmware and swithced to X all went too bad.

It is too pity as I really liked it as it was before.

I have had issues with this too with both pk3 and icd3 . today I noticed it was much worse when using salea logic no salea in use minimal connection losses , so I did a bit of googling . one suggestion was to use a powered usb hub.

well guess what it really works problem is gone

Then, what about using USB3 ports on the PC as they supply more current?

its not a power issue, even if I power the hub through its usb connection only the pk3 icd3 still work.
neither is powering the dev board in use.
I wonder if the pc usb ports behave differently when a hub is detected ?

[Ioannis]

Strange...

Also I noticed that when the PK3 is changing/loading new firmware, if the controller to be programmed is not connected, the IPE stays in loading for ever. No timeout, ne message, just waiting.
