Not working on ThinkPad A285 #14

Open TheSentry opened 4 years ago

TheSentry commented 4 years ago

First of all, thank for the great work so far. It's a pitty that it doesn't work for me though.

I've got a Lenovo ThinkPad A285 for work a few months ago, I flashed the BIOS to v1.41 today. LTE is working fine under Windows 10, I can surf the internet there.

I'm on Linux Mint 19.2 Cinnamon with a 5.0.0-36 kernel

$ uname -a
Linux bolle 5.0.0-36-generic #39~18.04.1-Ubuntu SMP Tue Nov 12 11:09:50 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I installed acpi_call_dkms via apt. This is my output before executing the script:

I know from previous attempts that it is 05:00.0

No modems are found so far. This is the output when executing the xmm7360 script:

$ sudo ./xmm2usb

OK!

So far, so good, the PCI device 05:00.0 is gone, but no new USB device appears

Is there anything else I can try?

TheSentry commented 4 years ago

I forgot to mention: The device manager in Windows 10 says that the WWAN module is connected via USB.

enzingerm commented 4 years ago

It seems that this is the same for various AMD based models (see #24). On my T495 the USB device does not appear after the script, either. Windows driver uses some kind of PCIe to USB translation layer, that may be the reason why the device manager shows the modem as connected via USB...
