Just adding some more findings, I'll probably be in bed later.
Plugging in my Minolta A2 in PTP mode, The Iyonix has
knowledge of it, and it shows
Class 6 Imaging
Sub Class 1 Still Image Capture
Protocol 1 P.T.P.
and once again, endpoints 3, it has this commonality with
the Sansa, and no non MTP/PTP devices seem to use it.
One quote: 'MTP is an extension to PTP and shares the same
class code'
The information shown may be related to the USB device tables
in ROM.(It would be good to have extension/replacement tables
in !Boot.)
A quick peek at libmtp, it is 'friendly looking' as long as
file i/o could be translated for Riscos USB.
