Dear Alan, In case of IN requests in the gadget driver, the gadget driver sends the requests to the dummy-hcd driver without waiting for the actual IN request from dummy hcd. That is, if suppose, in case of OUT request the gadget driver invokes the start_transfer routine and sleeps. This wait is signaled from the OUT command callback completion routine. In the same way, can I implement the IN request. That is, I will first invokes the start_transfer and sleeps. Then, when the IN request comes from the host then the dummy-hcd invokes the IN completion callback routine. Then, I will again invokes the start_tarnsfer routine, based on the IN request. For this, Shall I need to modify the dummy hcd driver? Please let me know whether it is possible or not.
