I have a USB combi keyboard/trackpad thing which is triggering "bad repid 33" frequently while attached (between a couple of times a minute, and once every few minutes). It does work but it's annoying.
Presumably this is because it has non-contiguous report IDs? Anyone have an idea how to handle it? Bus 000 Device 002: ID 045e:0800 Microsoft Corp.
