Yes , I have tried a few different cables.
Should I have the sd card inserted or not ?
It doesn't matter, unless the SD card is faulty and drawing a large current from the 3.3V rail.

Noted. I have been trying without the SD card anyway, so what is the next step ?

Did some digging,
and red that this message usually means that the device has exceeded the current limit of the portit means some general communication error, but either way it is worth a tryI, provided I have a notebook, would try to remove the sdcard, give the panel external 12/24v power, unplug the notebook from the charger and any other device connected to the mains voltage, and try the connection that way.
And / or an usb cable with multiple computer side connectors used by some mobile hdds.
I really do not know if it would help, but it is worth a try
-
Ok , so I just tried this , still no luck. I also tried running through usb isolator.
-
So what are the next steps ?

Unless you have someone local to you who may be able to diagnose the board, your best option may be to arrange with forum user W3DRK to send the board to him (he is in the US) and take a look at it. he is experienced at diagnosing and repairing Duets.

Can you assist me with a jtag reflash ?
-
Reliable shipping to USA and back would cost me quite a bit of money. Buying a new one would be a better bet for me.
I would really like to give the JTAG reflash a go.
What programmer do you use for flashing over JTAG ? and can you provide me with a wiring diagram ? Also , what binary should I flash ?
-
We have never flashed a board using JTAG, we flash using USB.
The symptoms you report are odd and it sounds to me more like a wiring or driver issue, except that you have tried multiple PCs. Have you measured the voltage on the +3.3V rail? Is any of the chips or the WiFi module on the Duet getting hot?

3.3 v rail seems good , the SAM chip is getting a little hot , around 40 degrees , the esp is ice cold.
Just another thing I noticed , if I press the erase or reset button , nothing happens , no flashing of any LED's

The SAM shouldn't get hot if it's just waiting to be flashed. Perhaps it is faulty.
Once the chip is erased and waiting to be bootloaded, I wouldn't expect the Erase or Reset buttons to flash any LEDs.
It's possible in theory to program the processor via the PanelDue port (and for the same reason, having a PanelDue connected might interfere with programming over USB, although in practice it doesn't seem to). You would need Bossa or SAM-BA and a serial-to-UART converter with 3.3V signal levels.
