Hello All, I am working on wanboard and the processor there is IMX6solo series . The USB controller is chipidea one . The drivers are all chipidea opensource driver. I have a requirement of connecting Iphone to it , where it will launch carplay on detection of carplay device . The flow is : 1> iphone connection to USB port 2> I have a user application which will be spawning on USB port for any change and once get it will check the type of device by libusb calls . 3> once detected as apple device , role switch for USB happens like my USB controller wil be switched to gadget mode and on disconnection it switch back to host mode (This is apple carplay specification) The problem here is if I connect and disconnect quickly , the udc_irq does not come atall . That means I feel the enumeration process for the device not completed and the disconnection happened . Due to this disconnect event does not come and my USB controller stays in gadget mode only . Any reason why the interrupt does not come atall ? atleast I was expecting the interrupt should be coming with some error which might not have been handled in driver . Thak you for any help in advance -- Anshuman -- 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
