Ok a USB3 hub allowed me to see the Bossa Program port!!! Standard USB hub failed...

Now trying a firmware upgrade configuration generation.

Or per my original request is there somewhere I can send this not inexpensive board to be repaired?

Ok I blew right past these steps because I did the erase procedure.

At this point I absolutely need the USB port to function.

Had I not done the erase procedure I could have tried a Raspberry PI communicating via the SPI data lines.

I expected the Bossa Port device ID to appear in the windows Device Manager after erasing the device.

At this point I need to know if there is replaceable chip between the USB port and the CPU to possibly resurrect this board. So that it appears to any USB host as a Bossa Port to reload the correct firmware.

@elmoret Ok a prefect storm of stuff.

Duet 2 Wify was in a 3D printed case that was destroying the USB cables as I used them. Enlarged the hole and the USB connection started working.

Duet 3 6HC board is still inoperative.

I am out of warranty by about a week.

I purchased a Duet 3 6HC board for a special project a year ago and the project got delayed and I put the board on the shelf and just now tried to use it.

I flashed an SD card with the initial network configuration of DHCP and expected it to appear on the network.

Then I tried the USB port and it was unrecognized by three different computers and cables under Windows 11, 7 and 10.

I then did the erase procedure and still no result other than powering the Duet board.

I do have an operational 3D printer with a Duet 2 Wify board and I am also unable to get the USB port to work on this board also. This board is way behind on updates so now leery of trying to update it if the USB port is not working.

Any suggestions ?

The project all of a sudden reached critically so I am going to have to buy another board, but I would still like the previous one repaired.

Thanks
