H A Dusb_usual.hdiff 33abc04f0420dceed0ebc2d1094019d3bb2b5c29 Thu Dec 06 06:36:45 CET 2007 Doug Maxey <dwm@enoyolf.org> usb-storage: Fix devices that cannot handle 32k transfers

When a device cannot handle the smallest previously limited transfer
size (64 blocks) without stalling, limit the device to the amount of
packets that fit in a platform native page.

The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever
used on a platform that has larger than 8K pages, you lose unless you
can convince the device firmware folks to fix the issue.
