Hi, This is regarding an issue we are facing with the gadget serial driver (driver/usb/gadget/serial.c). We have a hardware limitation and the USB hardware can only have bconfigurationvalue 0 or 1. In the CDC ACM config in gadget serial driver the configuration value is set to 2. Is there a specific reason why this was done? We see that, the three configurations listed in serial driver (CDC ACM, CDC OBEX, generic serial) cannot be present together as per the current implementation. Is there a specific reason why the configuration values were set as 1, 2 and 3 instead of setting all to 1? -- Anjana -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
