When you get a chance (or anyone else who has this problem), try the
attached patch, and add options BROKEN_OHCI to your kernel config file.
Please set hw.usb.ohci.debug=1, and send me the dmesg output of the
writes.  (When you copy the data to the media.)

Hmmm. I just thought of something.  Now is the data corrupt still correupt
on another system?  What I mean is did the data get written properly, but
just isn't being read back from the media correctly.  Unless you are
coping a file larger than memory size, the cmp just pulls it from memory,
not from the media.  The umount/mount forces a flush of the cache, and so
attempts to read from the media.

Thanks.
