Troubles establishing connection with wvdial - Invalid dial command error

Question

I am trying to run internet via HUAWEI E3372 on Debian. It worked on Windows but did not work on Debian.The error is this:

ATDT*99#
ERROR
--> Invalid dial command.
wvdial: utils/wvtask.cc:303: static int WvTaskMan::yield(int): Assertion
*current_task->stack_magic == WVTASK_MAGIC' failed.
Aborted

Here you are the issue info:

UPDATE

The configuration worked and internet got present actually. It was empty resolve.conf simlink so I copied /etc/ppp/resolve.conf one and it worked.

Anyway the error still remains and I would like to get rid of it.

Also note that I am doing all with Network Manager service disabled.

Answer 1

I had the same issue with the huawei E3372. I am on a raspberry pi (4) however. I solved it by adding max_usb_current=1 to /boot/config.txt. Apparently the E3372 silenty fails ("ERROR") when it does not get enough power and wvdial does not have any idea about it and just reports the "invalid dial command". Apparently the E3372 is power hungry on TX and causes this.
