[qmi-firmware-update] Flashing does not work properly with Sierra em9191 (5g modem)

Thu Feb 3 11:00:29 UTC 2022

Thank you for your comments.

My current status:

Multiple hardware power off helped. All my 3 modems are ready to work.

The last problem, I still have the issue with "error: couldn't open QMI
device: endpoint hangup". You requested verbose output:

What do you think?
In addition I see that my modems do not have ttyUSB* interfaces. I am not a
very experienced guy with the modems but in my previous work with 4G SIerra
modems I got ttyUSB* interfaces immediately after enabling the qmi open
source driver.
