USB is super convenient – just plug and play typically with stuff like this. No nasty drives, complicated configs, etc.
The control software and getting it to work in conjunction with other cards at same time is a whole other story.
It’s low cost too which is very important to most of us. Can afford to stock spares and double up on equipment.
My project, mates the USB sound card with an ARM based tiny computer (same general chip family as smartphones). Additionally bundling USB drive (flash) for OS install and file storage. Have to see how the USB performs with that all on the same bus. Should be fine for most uses though.
Looking at something the size of deck of cards but higher and with USB items hanging off it. So able to be stashed, stored, put in lots of places.
I plan on bugging folks here about their automation software for their stations, because that’s my intended use for this. To replace the big PC that is so common and offer a sort of hybrid of the PC and a Barix unit.
