But PA shows a broken string that it seems to have invented itself. So far, nobody has been able to explain why it does that (until you gave a suggestion below). If it had simply used the USB information, I would have been happy. > Cheking your product, it does indeed look like it's missing from the usb > ids database: > https://usb-ids.gowdy.us/read/UD/0763 > (as 2012 is missing).

Thank you. Finally a pointing finger. So why is udev giving us a mangled name?

I can do that too, but I think that when M-Audio actually manages to include useful USB descriptions, we should be able to use that in PA. Good information from the source (the vendor) should be encouraged. -- David K?gedal
