Hi, I have found out a way to connect an USB receptacle to USB host pins on SA1111 inside a HP Jornada 720. The modification is described at http://jlime.com/mw4/index.php/Hardware_documentation_jornada700_usbhost . Unfortunately it still doesn't work as expected - I have dumped some dmesgs here: http://filip.math.uni.lodz.pl/jornada/usb_host/ . The most interesting ones are these where kernel can retrieve proper identification numbers (optical mouse, card driver). But communication fails afterwards. Devices aren't usable. Things that surprise me in these logs: [ 1126.593375] sa1111-ohci 0400: OHCI 1.0, NO legacy support registers I've googled dmesg dumps and usually it says "with legacy support registers". OHCI 1.0 seems strange (SA1111 is 1.1 compatible), but i've seen that people have it in their logs. [ 1127.025533] hub 1-0:1.0: no power switching (usb 1.0) SA1111 is able to control power switching (and I have implemented the circuitry doing this with a TPS2043). This probably results from detecting it as a 1.0 host. I am posting this in hope that somebody could give me pointers about where to begin digging to fix this. I think hardware part is ok, because id numbers ARE somehow transferred. What do you think about it? I know this is an old hardware, but HP Jornadas are still widely used (especially by nerds) thanks to their unique balance of features (size, keyboard, battery life, slots etc.).
