I've been looking at this again with little luck so far. If I compile the various gadget drivers as modules (g_zero.ko, g_serial.ko, etc) I get:
modprobe g_zero.ko
modprobe: failed to load module g_zero.ko: Invalid argument
or
modprobe g_serial.ko
modprobe: failed to load module g_serial.ko: Invalid argument.
I am using the ISP1161 and the host side is, and has been, working for a long time. Any ideas/help would be really appreciated. This is the last major issue confronting our latest project and if I can get it working, I will finally be able to provide all of the wiki updates I've promised this group. Thanks, Alex
