Unfortunately, for USB Mass Storage, getting an accurate idea of how much
data there is to transfer (especially for commands that can only transfer
a fixed amount of information) is very important. So far, this is the
only case I've found where it's wrong, and I'm afraid I don't have the
time to discover where is is going wrong before 2.4.0
Would someone who is more familiar with these layer (Eric? someone else?)
please fix this? And let me know when you do so I can test it. I imagine
that it's probably, as you indicate, just a quick little fix to some relic
code. Hopefully we can get this in before 2.4.0
