Hi, I have spent some time on my 08:00.0 Wireless controller [0d40]: MEDIATEK Corp. T700 5G Modem [5G Solution 5000] (rev 01) The reason why it was not working from the start was that in my initial setup I had no xxd binary. I did not see any related error log in journalctl, neither when I run ModemManager in terminal. Is it possible to improve error handling?
Thank you for your work, this was just a cosmetic issue, but hard to find, when you do not know where to look.
