At the moment I can only connect to the Modduox via my laptop.
With the desktop the connection fails, no matter which USB port the Modduox is connected to - I have tried them all. I used Firefox and Chromium, I had the extensions disabled.
I didn’t find anything in https://wiki.moddevices.com/wiki/Troubleshooting and now I have no more idea. Have I forgotten something important? What can I do?
Desktop: Debian, XFCE4
Laptop: Debian, Gnome
lsusb on the desktop say when the Duo is physically connected? If the Duo is detected you will see something like
0525:a4a2 Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget. If this is not the case, we got a problem on the USB hardware level.
What network devices are present when running
ip a? Usually the last device in the list is the Duo. Does it have an IP address assigned? If there’s an interface with no IP, is the network manager running?
Also try running
sudo journalctl -fk before plugging the Duo into the USB port and look at the USB and network related messages.
The moddoux is recognized by lsusb.
However, according to “ip a” it is not assigned an IP address.
XFCE4 has a network manager in autostart. But no matter if it is switched on or off, the moddoux has no IP address.
“journalctl -fk” shows me on some USB ports that the USB cable is defective, on other USB ports it detects the Moddoux without error messages.
With the laptop, the Moddoux has an IP address, everything runs smoothly - plug and play.
Ok then try
dhclient <insert interface name here> and see if you get an IP.
This just seems like a quirk of XFCE not automatically assigning or connecting
Thanks for the quick and successful help.
Everything works now and: I have learned something.
