You are trying to see when it fails?
No, it's okay for the computer to ask the device for a large amount of data. If the device can't fulfill the request, it will just send whatever data it has. The problem is that the USB hub driver in your computer is asking the internal hub in your drive for a 1-byte status report, but the internal hub is sending back more than that -- maybe as much as 64 bytes (that's what your Windows trace shows). The patch will make the hub driver ask for a 64-byte status report.
