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.
