Greetings, I'm trying to find the simplest way to develop a bulk mode gadget that exposes a standard userland IO interface. I've not been able to find anything suitable but if such a beast does exist please do point me in the right direction. Failing that please read on. The appliance collects data via video and other sensors. There is an intermediate userland processing application that sources from video (V4L2), SPI, etc. and would write its output to the host via USB. V4L2 on the target H3 SoC is only (currently) supported with a 3.4.X kernel. Thus newer gadget FS options marked as experimental. This may be a significant constraint, I am not yet sure. This is an embedded appliance and g_zero does work. Thus I am minded to extend g_zero, adding fileops etc. so it appears as a standard character mode driver in /dev. Read() and write() would simply be hooked in to the source_sink_complete() handler. Does this sense? Any comments/thought much appreciated.
