I’m using a ublox SARA-U201 USB modem. With the linux version from toradex it is working. I can start it with pon and have a internet connection. With my own linux version, everytime I start the system, the modem is in air plane mode and even when I change the mode, I can’t get it working. I don’t know, where there is a difference between the to linux. One thing I found is, that with your version, I see “usb0”, when typing “ifconfig”, with mine not.
Do you any suggestion, what to change?
Best regards, PrS
