Hi,
I have a MC7304 upgraded to SWI9X15C_05.05.58.00_GENEU-4G_005.029_000. And after upgrade, no serial ports show up neither on Windows nor on Linux.
On Windows, I’ve tried different driver versions. Namely v4773, v4277, v4431 and v4743. It does show up as Mobile Broadband Device, but nothing else.
Linux behaves similarly.
Here’s output of dmesg, after inserting the device:

I’ve tried blacklisting the cmc_mbim, cdc_acm, and cdc_ncm modules, but no driver is loaded for device then.
Windows is 10 1709
Linux kernel is 3.10.0-229.14.1.el7.x86_64
What am I doing wrong?
PS
Here’s also output of lsusb -v, regarding the device:
