I'm obviously missing something here but am not quite sure what. My usermode code* is set up to emulate an existing FX3 device. Bulk reads and writes are all fine as are vendor-specific commands that are host to device. However anything that is device to host never appears on the wire. The generic handler for IN vendor requests is simply writes 'length' bytes back on the file descriptor that represents EP0. USB packet sniffers show that data never gets out.
Does it need to ACK or clear anything first? Incidentally is there any reason why EP0 itself does not appear in the /dev/gadget tree?
