EG915N-EU driver file for linux kernel 5.15.0-107-generic

Technical Subjects Driver
1

I connect the device via USB and I did not have a problem in Windows, but I could not install the Linux driver and connect it to the internet. When I first plugged it in, dev/ttyUSB0, 1, 2, 3 were visible, but after a few kernel operations, it does not appear either. I would be happy if you help.

Please check

dmesg | grep option

Please try


modprobe  option

echo 2C7C  6002 > /sys/bus/usb-serial/drivers/option1/new_id

There is new_id under /sys/bus/usb-serial/drivers/generic.

If so you can try the

echo 2C7C  6002 > /sys/bus/usb-serial/drivers/generic/new_id

It seems not like a standard Ubuntu.

OK, now it’s back to normal, the ports are visible, but I’m still not sure if I installed the drivers. I cannot use the internet.

You need to send AT command to set up data call.

AT+QNETDEVCTL=1,1,1
