Interesting. This log shows no errors at all. It's got a couple of reads followed by 12 writes, and they all completed successfully. Judging from this, I would say that the problem must lie somewhere else, not in the USB driver. I don't understand why the same test should behave differently depending on whether the device is attached directly to the host or not. If you also have a non-EHCI host in your system, it might be worth trying the same tests using that controller. Maybe another possibility is a flaw in the filesystem code (I'm guessing wildly here). Is it possible to use a different sort of filesystem and repeat the tests? And related to that, did your original command ever end up writing anything to the md5sums output file?
