Hello I would like to make a device driver for printer. So, I want to use g_serial to develop device driver, but there are some questions.
There are two requests. Those are Standard Request and Class-Specific Request. In g_serial, it handles Standard Request in gs_setup function which is called by net2280_irq in net2280.c However, it does not handle Class-Specific Request. Of course, it does not need to handle Class-Specific Request, but if I want to insert codes handling Class-Specific Request into g_serial.c, how can I do it? In file_storage.c from /driver/usb/gadget, there are two parts handling Standard Request and Class-Specific Request. However, in my opinion, there is one part handling Requests in net2280.c, that is... tmp = dev->driver->setup (&dev->gadget, &u.r); If so, how file_storage.c distinguishes two Requests? "distinguish" means that one case, it calls 'class_setup_req' function and another case, it calls 'standard_setup_req'. If you know any references for gadget driver of printer, could you tell me the way how I get? ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
