Hi Corbin,

Thanks for your help, Corbin! :)

neither lsusb nor usb-devices do list the device. 

Another CH340 based board do register correctly and ttyUSB is created.
Therefore (I think) the infrastructure of my Gentoo LINUX can handle
such board correctly and this [CENSORED] one ist either send without
any firmware or simply demaged.

I need the help of one who has solved similiar problems
with an NodeMCU v3 Lua (ESP8266)-board...sigh...

Best regards,
Meino

What's running on the board? I'm not familiar with it or arduinos at all but it 
looks like it's being
detected and then disconnected. Are you trying to program the board through 
USB? If so, and since
it's detected when you reset the board, my guess is that it's got some kind of 
bootloader that is
initializing the UART->USB adapter and passing control to whatever firmware is 
already loaded, and
that firmware is not driving the UART/USB adapter. If that's the case the 
board's manual should tell you how
to program it.

Hi,

There is an according module in the driver (compiled

When I connect the ESP8266 board to my Gentoo PC
nothing happens (dmesg shows nothing).
When pressing RST on the board, I see this sometimes:

If memory serves, udev/eudev generates the nodes/devices in /dev now.
To get the correct hardware ID, it uses a specific database.

The hardware ID's database may need to be updated ( or supplemented ).
The package "sys-apps/pciutils" has the hardware database included in it.

I have a 990FX chipset MB that is constantly ID as a 880 chipset board.
No info on 990FX chipsets found in the hardware ID's database.
The kernel keeps applying a 880 chipset workaround for the PCI bus, 
every boot.


Same problem I think, different hardware.
