Please open a new issue in ModemManager if that is the case, see. The L860 model should be usable since 5.14, it is possible that L860 model can be unlocked similarly as EM120 model with correct FCC unlock operation.

Using intel-media-driver provides good graphics performance. However, this can be expensive in terms of power consumption (around 2-3 W), and may be not needed with recent kernels (e.g., 5.14). If you are getting laggy/stuttering UI and mouse movements in your desktop environment add i915.enable_psr=0 to your kernel parameters. Then make sure to select the DMIC16kHz as your microphone. Edit /etc/nf and add /etc/udev/hwdb.bin to the FILES array (i.e.to do that, you'll need your hwdb.bin inside your initramfs. To get them to properly work, usbcore must register snd-usb-audio before the snd_hda_codecs are processed. They are individually configurable, but also grouped as a single DMIC and DMIC16kHz. Apply the "Laptop" preset (recommended) or "Advanced Auto Gain" preset as per your preferences. If you use PipeWire or Wireplumber, install EasyEffects and the EasyEffects presets bundle.
