The Wikipedia entry has a pronunciation guide:
English: [bɑːrsəˈloʊnə]
Catalan: [bəɾsəˈlonə]
The first a is a schwa and the o isn't rounded. Honestly, it looks quite similar to English, to the point where there might be some English dialect that sounds exactly like that.
This sounds like some silly bug in libinput.
There's nothing in wayland that would care about whether a mouse was connected wirelessly, but libinput may not be detecting it properly when wired. I'd try reporting it, the fix is likely to be trivial.
