Hi there, and a Happy New Year!

I switched hardware and can't get my Huawei Stick to work again.
The mode is set correctly but some how it seems to switch back to storage mode:

I have a 5V/3A Hub powering the Stick so power shouldn't be the issue here.
I tried different cables.

When I try to send an SMS I get:

Any ideas?

Thanks, Tino

Hmm, power issues would have been my #1 hypothesis.

If the stick has no defects - I assume you have used it previously with no issues - then the focus is on the host system. Can you specify it?
