The usb_f_printer gadget driver uses a default q_len value of *0* which prevents any IO from occurring. Moreover, once the driver is instantiated it is impossible to change the q_len value. The following patch uses a default q_len value of 10 which matches the legacy g_printer gadget driver. This minimizes the possibility that you end up with a non-working printer gadget. It is still possible to set the q_len to a different value using the configfs path of the same name.
