Does Windows treat the expansion C cards as hubs? Audio Interface Issues

I use my laptop for music and I have been having issues with the audio driver/devices crashing. It’s acting like its being plugged into a cheap hub.

Hi,
When you say “acting like its being plugged into a cheap hub”, what do you mean?
The expansion slot USB C cards are not hubs, they just extend the USB C wires a bit, so passive in nature.
There might be limits on how much power can be sourced from the FW13 USB-C ports.
A way to diagnose that is to plug the FW13 into an external USB-C hub, with the USB-C hub having its own power source, thus not needing the power form the FW13.
You might have more luck with that.
If it does help, this points to a USB-C port power compatibility problem with the USB audio device you are trying to use.

We use a 12th gen i7 FW13 with 16GB RAM and a Focusrite Gen3 4i4 for (radio outside broadcast) audio production. All 4 analogue outputs of the Scartett are fed to a down-stream mixer. We do not use the analogue inputs in practice although I experimented with VT when we first configured the laptop.

The software environment is Windows 11 Pro 23H2 coupled with mAirList . We’re using whatever “drivers” that the Scarlett pushed when first plugged in.

The Scarlett is connected directly to a FW USB-C expansion card. There is no additional PS.

This configuration has been in service for a couple of years and has proven robust and dependable.

From this I would posit that the failures you’re experiencing are unrelated to USB connection or stock drivers. Colleagues have told me that Windows 11 24H2 has caused a lot of issues although not the ones you mention. I have no experience with Studio One 7.
