Those devices have a behaviour different than usual sms1100 and sms2270: they start with one USB ID (devices in cold state), but after firmware load, they get a different USB ID. This weren't docummented at the driver. So, the patches that added support for sms2270 broke it. Properly documment it, and provide a debug log that allows to follow all phases of the device initialization: smsusb_probe: board id=13, interface number 0 smsusb_probe: interface 0 won't be used. Expecting interface 1 to popup smsusb_probe: board id=13, interface number 1 smsusb_probe: smsusb_probe 1 smsusb_probe: endpoint 0 81 02 64 smsusb_probe: endpoint 1 02 02 64 smsusb_probe: stellar device in cold state was found at usb\4-2. smsusb1_load_firmware: sent 38144(38144) bytes, rc 0 smsusb1_load_firmware: read FW dvbt_bda_stellar_usb.inp, size=38144 smsusb_probe: stellar device now in warm state usbcore: registered new interface driver smsusb usb 4-2: USB disconnect, device number 52 usb 4-2: new full-speed USB device number 53 using uhci_hcd usb 4-2: New USB device found, idVendor=187f, idProduct=0100 usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 4-2: Product: SMS DVBT-BDA Receiver usb 4-2: Manufacturer: Siano Mobile Silicon smsusb_probe: board id=1, interface number 0 smsusb_probe: smsusb_probe 0 smsusb_probe: endpoint 0 81 02 64 smsusb_probe: endpoint 1 02 02 64 smsusb_init_device: in_ep = 81, out_ep = 02 smscore_register_device: allocated 50 buffers smscore_register_device: device ffff88012a00bc00 created smsusb_init_device: smsusb_start_streaming(...). smscore_set_device_mode: set device mode to 4 smsusb1_detectmode: 4 "SMS DVBT-BDA Receiver" smsusb_sendrequest: sending MSG_SMS_INIT_DEVICE_REQ(578) size: 12 smsusb_onresponse: received MSG_SMS_INIT_DEVICE_RES(579) size: 12 smscore_set_device_mode: Success setting device mode. smscore_init_ir: IR port has not been detected smscore_start_device: device ffff88012a00bc00 started, rc 0 smsusb_init_device: device 0xffff88002cfa6000 created smsusb_probe: Device initialized with return code 0 DVB: registering new adapter (Siano Stellar Digital Receiver) usb 4-2: DVB: registering adapter 0 frontend 0 (Siano Mobile Digital MDTV Receiver)... smscore_register_client: ffff88012174a000 693 1 sms_board_dvb3_event: DVB3_EVENT_HOTPLUG smsdvb_hotplug: success smsdvb_module_init: Signed-off-by: Mauro Carvalho Chehab Tested-by: André Roth Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/usb/siano/smsusb.c b/drivers/media/usb/siano/smsusb.c index 74236b8007c7..33f357510194 100644 --- a/drivers/media/usb/siano/smsusb.c +++ b/drivers/media/usb/siano/smsusb.c @@ -491,15 +491,26 @@ static int smsusb_probe(struct usb_interface *intf, } if (id->driver_info == SMS1XXX_BOARD_SIANO_STELLAR_ROM) { + /* Detected a Siano Stellar uninitialized */ + snprintf(devpath, sizeof(devpath), "usb\\%d-%s", udev->bus->busnum, udev->devpath); - sms_info("stellar device was found."); - return smsusb1_load_firmware( + sms_info("stellar device in cold state was found at %s.", devpath); + rc = smsusb1_load_firmware( udev, smscore_registry_getmode(devpath), id->driver_info); + + /* This device will reset and gain another USB ID */ + if (!rc) + sms_info("stellar device now in warm state"); + else + sms_err("Failed to put stellar in warm state.
