I don't know for sure but it sounds like the issue could be to do with SysEx. From what I understand, the SysEx files can be larger packets and when sent via USB over a certain packet size it can cause problems, these can be avoided usually by adding a small delay between packets, and keeping the packet size to a limit of (I think) 256 bytes. Some software lets you edit those settings but not always.
