It's likely that the block layer is breaking up the EXT4 write into
several transfers, since usb-storage limits overall transfer size to
120 KB. In any case, I added more debugging in the last patch to print
the number of TRBs necessary. That way we can verify the patch to limit
the number of scatter-gather list entries is working.
