Thanks, the message id there led me to
http://thread.gmane.org/gmane.linux.usb.general/117272
which has the whole thread.
Including a v3 which is slightly different to what has been posted here
so far:
http://thread.gmane.org/gmane.linux.usb.general/117272/focus=118786
It uses dma_set_mask_and_coherent rather than individual calls to
dma_set_coherent_mask then dma_set_mask, which the various feedback in
the thread seems to indicate is more correct.
So that's the one I intend to apply along with the Kconfig part of
http://thread.gmane.org/gmane.linux.usb.general/117272/focus=118784
(post beer festival though I'm afraid ;-))
Ian.
