Pit

If works for me (SPF 107H USB-ID 04e8:2035 / 2036). Great (and unbelievable short time to make it happen)!

Concerning the switch back from monitor mode after a couple of seconds for some Samsung SPF I have found on "http://pyframe.blogspot.de/2011_12_01_archive.html" this information (it's from a python script). # This control function is required to keep the frame permanently in Mini Monitor mode. # When the frame is switched to Mini Monitor mode, it remains there for a few seconds, but # then switches back, unregistering from the USB bus. # This function is needed only once after connection of the frame, but it does not seem # to do any harm when transfered with every picture transfer dev.ctrl_transfer(0xc0, 4 ) Perhaps you can add this byte sequence to the contol code sent to the frame, to solve the problem of the not permanent "mini monitor" mode.
