RFLink: Error opening serial port!

Hello everyone,
(Sorry... Google translate
)
It's been 3 years since I was running with RFlink without any problem.
But since September 2, impossible to communicate with the arduino! (I changed the USB cable and even the arduino in doubt) on a Raspberry 4 with raspbian above
But nothing works!
In domoticz, you can not select a "serial" port when configuring hardware.
domoticz Version :
Version: 4.11280
Build Hash: 367ff3426
Compile Date: 2019-09-05 09:21:59
dzVents Version: 2.4.28
Linux recognizes the arduino :
Code: Select all
pi@raspberrypi:~/domoticz $ lsusb -v
Bus 001 Device 004: ID 2341:0042 Arduino SA Mega 2560 R3 (CDC ACM)
Couldn't open device, some information will be missing
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 1.10
bDeviceClass 2 Communications
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 8
idVendor 0x2341 Arduino SA
idProduct 0x0042 Mega 2560 R3 (CDC ACM)
bcdDevice 0.01
iManufacturer 1
Will any of you have a solution for me: D
Thank you!

Mmm
Can you try the following while having a terminal open:
- Unplug USB
- Replug USB in Pi.
- Type
There should be something mentioned about your USB port.

Clearly visible is the DIsconnect indeed.
I'm missing the assignment of /dev/ttyUSBx to this device.
Will show nothing I guess. So there is your known 'problem'.
The device serial should be known indeed by the Pi.

Let's go for:
-Unplug
-Plug in the device
And check with

I just found the solution ...
I boot on an nfs server. I just transferred the files from the / boot folder to my SD card.
no problem with the RFLink module after reboot
Thank you again for your help !
For information, on RPI4 the way to the USB port is
Code: Select all

Hi @arnodu59,
I think I have the same issue. Could you give me more informations for the solution ?
En français si tu préfères en MP.
Thanks.
