I could be misremembering but I believe the guitar center waiting period isn't _just_ to make sure it's not stolen (I kind of doubt they're actually doing anything like an investigation) but also because legally their used equipment side of business has to operate like a pawn shop, in that they aren't allowed to sell something they've "bought" until after the window for the pawner to buy it back expires.
I packaged that driver on the AUR, since I’ve got the same device. I can’t get the binary blob to work (admittedly, I haven’t tried very hard) and it’s not high on my list of priorities so I’m okay using it as a dumb MIDI tool.
Yes Claude is impressive in HW-Development. It knows all those magic numbers and how chips work. i even use it to do development for Power delivery Systems.
