Hello

I would like to connect a 3d printer in usb on my cubietruck, except that when I connect it it does not detect the dev port.
I do not know what to do.
I do not know which USB driver works on the cubietruck.

 

dmesg :

[37883.769292] usb 4-1: new full-speed USB device number 4 using ohci-platform
[37884.038336] usb 4-1: New USB device found, idVendor=1a86, idProduct=7523
[37884.038354] usb 4-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[37884.038365] usb 4-1: Product: USB2.0-Serial

 

on which port dev is connected the printer?

Which kernel/image are you using ?

What is the output of "grep CH34 /boot/config-<kernel number>" command ?

It should be something like : 

CONFIG_USB_SERIAL_CH341=m

Then, you should have it as /dev/ttyUSB0 ...

Is it shown when doing "lsusb" ?

The dmesg doesn't report something like : 

[    7.992734] usbserial: USB Serial support registered for ch341-uart
[    8.001849] usb 8-1: ch341-uart converter now attached to ttyUSB0

Strange ...

 

What "lsmod" is reporting ? "ch341" should be present ...

root@cubietruck:/boot# lsusb

the only mention of USB in the dmesg is in the first message.

Óooh ! I didn't notice carefully your previous reply :

 

Kernel is 4.14.14-sunxi but you config is config-4.14.18-sunxi ... Kind of mismatch ...

Do you have the module in /lib/modules/4.14.14-sunxi/kernel/drivers/usb/serial/ch341.ko or in /lib/modules/4.14.18-sunxi/kernel/drivers/usb/serial/ch341.ko  ?

Maybe expected missing path is the cause of your issue ...

a path problem?

I had updated the linux-config-sunxi but not the dtb, and so after having updated and restart the CB, I finally get the default ch341, by cons I lost the wifi, and it is no longer available in armbian-config ....

Of course ... You have kernel 4.14.14 and modules for 4.14.18 ...

This is not related to path issue. I don't own CB, so, are you saying that WiFi under 4.14.14 was working and not in 4.14.18 ?

no, it's the built-in wifi. that's what it gives me:

That is what I wished to see ... So, probably not a DT issue ...

I found !!! it's not "iface lo init loopback" but "iface lo inet loopback"

and it is not me that generates this error.
