Error Short to Ground reported by driver(s)

Sorry to hear you've had some trouble with your replacement board. When you say it no longer works, what exactly works or doesn't work?
-
Thanks for you concern.
It just won't connect in any way.
Wi-Fi doesn't connect nor via usb on Windows or Mac.
I've attempted multiple resets because eventually that is how I got it to connect via usb when I 1st got this board. -

Does the blue LED on the wifi module illuminate at all when powered on?
What LEDs are lit on the board itself?
Do any of the components get hot to the touch after being powered for a short time?
It's quite unusual for a board to go completely dead like that. Let alone have troubles two in a row. I understand that you've gone through some trouble getting it to work previously along with getting the replacement working, so I understand if you don't wish to go through any more hoops. So if you don't wish to go through any more trouble shooting and would prefer a warranty replacement that is an option, though it would still help to understand what has failed.

@phaedrux
I don't mind helping you understand what went wrong.
Here's the status of each LED (see photo)
NOTE: the STATUS LED is flashing red slowly.
This is connected via USB to my mac mini M1, but not recognized by macOS
I have also attempted to connect it to a MacBook Pro 2017 and on both machines via Parallels to a Windows 11 and Windows 10 virtual machine. Win11 on mac mini, Windows 10 on MB Pro.
There is no recognition of the board on any machine.

The status light flashing indicates the firmware has been wiped.
With the previous board I think you had gotten it to show up on the Mac with bootcamp? I suppose that isn't working this time?

That is correct. Sorry, I said the MB Pro was via Parallels, it's actually BootCamp.
I have attempted to "reset" the board multiple times. It eventually worked the first go-around, but it's not working this time. -
@phaedrux just one thought, could the communication be interfered by ground loop?

@davidewen as last time...
Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.
Sorry for the inconvenience.
For the new board it would be a good idea to test the usb terminal connection right away to establish that it works reliably with one of your computers.

Got board #3.
Opened box, attached Wi-Fi antennae, attached supplied USB cable, powered up.
Not recognized by macOS.
Status of LEDs.
STATUS = slow flashing red
5v = solid red
3.3v = solid green
ESP = solid greenPowered on & off multiple times. None of the attempts resulted in recognition by macOS.
Moved from mac mini M1 computer to Mac Book Pro w/Intel.
Same results as mac mini.Connected via Boot Camp
Same resultsIf I understand correctly, the slow flashing STATUS LED indicates no firmware?
So, I attempted a 2x fast click of the RESET button.
STATUS LED quickly flashes. ESP LED goes off.
After 10 minutes, nothing happened so I 1x clicked the RESET button and board returned to status above. -
Just to confirm, you're following this? https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Duet_3_Mini_5_WiFi_Ethernet
The Duet 3 Mini 5+ supports an easy mechanism for updating the firmware directly.
Connect the Duet to a PC (Windows, Mac or Linux) using a USB cable
Press the Reset button twice quickly in succession. The Status LED should cycle slowly between dim and bright. This indicates that the bootloader is active.
A new Mass Storage device should appear on the PC. Identify its drive letter (Windows) or mount path (Linux).
A directory listing of this mass storage device should show three virtual files. File CURRENT.UF2 is the existing firmware on the Duet.
Copy the new Duet3Firmware-Mini5plus.uf2 file to the mass storage device
The Status LED will flicker as the firmware is being written, then the Duet will reboot using the new firmware. The mass storage device will disappear from your PC and the Duet 3 COM port will appear.Also, the boards ship with firmware already applied and are tested before going out to vendors. There should be no need to wipe or reflash firmware out of the box.

I've attempted to follow the FW instructions, but the board just isn't recognized, even with BOSSA and 2x quick press of the RESET button.
I even wrote the DuetWiFiServer.bin file to a blank SD card to see if that would work.
These are the computers I've attempted to connect this board to.
None recognize the board in system/device manager or as a storage device.Mac mini (M1, 2020)

I did not purposefully or accidentally wipe or reflash the FW. (initially) Once the board was not detected after multiple on/offs, I did 2x click the RESET button to attempt connection that way.
This is the 2nd board I have received with this problem.
Out of the box = no connectivity.
Out of the box, connect to USB, STATUS LED slowly flashes red, 5v LED on, 3.3v LED on, Wi-Fi LED on.I would be happy to:
Do a screen share to work together to solve the problem
Send you this board so you can test it.I don't know what else I can do on my end.

Bossa doesn't work with the mini5+. The 2x quick presses of the reset button are required to make the board show up as a USB storage device in finder. Then you copy the firmware file onto that drive to write it.
Can you confirm that's where you're looking?

It does not show up in Device Manager or as a USB device.I will however double check when I get home this afternoon.

You cannot use bossa with the Mini5+ to flash the firmware. That just won't work.
When the reset button has been pushed twice the board turns into a USB thumb drive that shows up in windows explorer or finder etc as a usb storage device. You can then copy the firmware there.

Using Bossa and 2x the RESET button does not show the USB in Windows Exp.
NOTE: The Kryptonite drive is a Crypto currency miner, not the Duet board.STATUS LED is flashing fast.
Wi-FI LED is off.
5v LED is on.
3.3v LED is on.

What should happen when you press he Reset button twice in quick succession on the Duet 3 Mini is that the red STATUS LED cycles between bright and dim. When that happens, the USB drive should appear on your PC. Make sure that the USB cable you use is not a power-only cable for charging smartphones etc.
If the STATUS LED blinks slowly (once per second) then it is running firmware.
If it blinks quickly then it should blink a number of times, stop, and repeat. In that case the number of blinks is an error code.
