C-U0012 Unifying Receiver and nRF52840 MDK USB Dongle - Pairing Timeout

[TW-D]

Hello, after discovering your project in the MISC 126 magazine, I started the adventure but after several efforts I always get a too long delay during the pairing phase.

Here is the detailed procedure I followed :

Installation of "munifying"

:~$ sudo apt update
:~$ sudo apt-get install golang-go libusb-1.0-0 libusb-1.0-0-dev
:~$ go install github.com/mame82/munifying@latest

Flash "Logitech C-U0012 Unifying Receiver" With "RQR39.06_B0040"

:~/LOGITacker$ wget https://raw.githubusercontent.com/Logitech/fw_updates/master/RQR39/RQR39.06/RQR39.06_B0040.shex

:~/LOGITacker$ lsusb
[...] ID 046d:c52b Logitech, Inc. Unifying Receiver

:~/LOGITacker$ sudo ~/go/bin/munifying flash --hexfile ./RQR39.06_B0040.shex

:~/LOGITacker$ lsusb
[...] ID 046d:c539 Logitech, Inc. USB Receiver

Flash "nRF52840 MDK USB Dongle" With "LOGITacker"

:~/LOGITacker$ wget https://github.com/RoganDawes/LOGITacker/releases/download/v0.2.3-beta/logitacker_mdk_dongle.hex

:~/LOGITacker$ python3 ./uf2conv.py ./logitacker_mdk_dongle.hex --family 0xADA52840

"Logitech C-U0012 Unifying Receiver" And "nRF52840 MDK USB Dongle" Pairing

:~/LOGITacker$ sudo ~/go/bin/munifying info
:~/LOGITacker$ sudo ~/go/bin/munifying unpairall
:~/LOGITacker$ sudo ~/go/bin/munifying pair
TIMEOUT :(

NOTE : All these operations have been done under Ubuntu 22.10

Thank you for your help.

Finally, I had forgotten to do LOGITacker (discover) $ pair device run before :~/LOGITacker$ sudo ~/go/bin/munifying pair. Thanks to the author of the article :)
