My experience is not very wide. However I think it would be okay to cap the number at, say, 16. Probably 99+% of URBs will use fewer than that. A typical user of Iso URBs is USB audio; maybe Clemens can provide some guidance. If anyone ever needs to see more, they should be able to do it by changing a #define somewhere and rebuilding.
