I am starting a new hardware driver for the gadget framework. Enumeration works fine, the host recognize the device and the host class driver is loaded as expected. The kernel message on the host system is like this: [25250.196665] cdc_subset 6-1:2.1: usb0: register 'cdc_subset' at usb-0000:00:1d.0-1, Linux Device, ae:6d:04:54:4e:b0 [25260.872006] usb0: no IPv6 routers present My problem: After the enumeration I receive a 24 bytes packet on ep 0. How to handle that packet? There is no request pending in the queue so I could not copy the data from the fifo to the request buffer and call the req->complete callback. Is there any callback in any structure where I can send the packet to the upper gadget layer? Maybe there is any starter documentation on this topic?
