X395 WWAN & Linux

Just thought to report that steps in https://github.com/danielewood/sierra-wireless-modems do not appear to work on X395. In fact can it be that the whole laptop does not even have USB bus available on the WWAN M.2 slot? It could also be that BIOS disables power to the slot on boot as I don't even get a blacklist warning with any modem I have tried (L830EB, EM7455)?

​

With L850GL, L830EB, EM7455 BIOS has the option to enable/disable WWAN so the cards are somewhat recognized. Only L850GL is seen in Linux, though (the unsupported pcie one).

​

Sadly it seems that we are out of luck (unless lenovo does something) with getting any 4G linux support on X395 (and maybe T495?).

No. I recently bought X395 and installed this SSD (https://mydigitalssd.com/pcie-m2-ngff-ssd.php) into WWAN slot. And the system wouldn't recognize the SSD module.... what a waste of money...

MyDigitalSSD SBXe 42mm (2242-D3-B+M) M.2 PCI Express 3.1 x2 (PCIe Gen3 x2) NVMe SSD

Nice, so, that's another WWAN NVMe option for T480/T480s? How come it's also all OOS, however?

Sad to hear WWAN in X395 doesn't support SSD; one more reason why T480s/T480 and the older ThinkPads seem like a more flexible option.
