I have already done the udev settings and the board is not detected when I plug the reel board “Debug USB” connector to my PC
I fear my board is defective.
I wonder what happens when a Reel board is plugged in.
Did you remember to turn the board on using the power switch? Are any of the LEDs on the board lit?

Does anybody have one ?
Yes. I have a couple of those boards. I have no issue with flashing
I have one and it's working for me also. Try plugging it in while
'udevadm monitor' is running. You should see a bunch of lines related to
device creation.

Hi Marti,
in fact I tested that as well.

I am running an Ubuntu 18.04 O.S.
I tried connecting to my PC the Reel Board on Debug-USB port and then to nRF-USB port. Both are no working. Which one is expected to be used?

I added the udev rule (it's also explained here [1])

$ cat /etc/udev/rules.d/90-daplink.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="0d28", ATTRS{idProduct}=="0204", MODE="664", GROUP="plugdev"

$ sudo udevadm control --reload-rules

Unfortunately 'lsusb' and 'dmesg' don't show any activity.
I tried also the udevadm monitor command, no events are detected.

$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
...nothing here...

Could you please send me the output on your side?
Perhaps my board is defective?
