That's probably it! Realistically, though, allowing st to override the block limits was wrong. Most drivers (except USB) don't set these arbitrarily, they usually represent fundamental hardware limits. If you force down a transaction that's larger than they declared themselves capable of, they'll do strange things like wrap descriptors or truncate the transaction, which will cause silent data corruption. Hopefully we can figure out how to get USB working.
