Only the fact that USB is a nightmare to work with. No, honestly, we have a continuous stream of USB related problems with the current USB code. As I understand it this results from the ever more diverging USB implementation in U-Boot and e.g. in the Linux kernel. The latter has received a lot of work which is simply not possible by reading datasheets and writing software according to those. This involves a lot of testing on literally thousands of different HW incarnations and on working around the discovered idosyncracies of the parts. Sometimes I get the impression that we would save a lot of headache by starting afresh and porting the current Linux code into U-Boot thus leverage all this, but nobody yet dared to start such a feat. For the problem at hand, you may try to test variations on your setup, e.g. by introducing different hubs in different combinations. I'm pretty sure that this will change the situation - sadly may be not for the better.
