[PATCH] ehci, qtd submit and completions
> ... usb-storage gets unhappy when

> devices. ...
I don't know if that problem is resolved, but this patch
makes the question moot by handling an earlier error correctly.
The patch updates an incorrect test, so a short read will now
be treated as one. Please merge.
This lets storage behave again. As in, "mkfs -c" then copy
about 8 GB around, then 'dbench'.
