There is same ID used by af9015 and it913x. Both drivers are loaded when that ID appears. What I understand *both* drivers, af9015 and it913x should detect if device is correct or not. If device is af9015 then it913x should reject it with -ENODEV most likely without a I/O. If device is it913x then af9015 should reject the device similarly. And you must find out how to do that. It is not acceptable both drivers starts doing I/O for same device same time. regards Antti > ----------------------------------------------------------------------- > [ 1.264018] usb 2-1: new high speed USB device using ehci_hcd and > address 2 > [ 1.382487] usb 2-1: New USB device found, idVendor=0ccd, idProduct=0099 > [ 1.382490] usb 2-1: New USB device strings: Mfr=1, Product=2, > SerialNumber=0 > [ 1.382492] usb 2-1: Product: DVB-T TV Stick > [ 1.382494] usb 2-1: Manufacturer: ITE Technologies, Inc. > [ 1.385073] input: ITE Technologies, Inc.

I recall a similar problem exists with the DiB3000M-B driver with its faulty IDs. A solution may be for Cinergy to have its own module with extern access to both dvb_usb_device_properties structures and dvb_usbv2_probe them twice.

Well, builtin modules are loaded before, so if it931x is built with 'Y' and af9015 with 'M', then it913x will be the first one. As a general rule, don't trust on one being loaded before the other: the best thing to do is to detect different USB ID and bcdDevice at the USB Table. It seems that the it931x variant has bcdDevice equal to 2.00, from Damien's email: idVendor 0x0ccd TerraTec Electronic GmbH idProduct 0x0099 bcdDevice 2.00 iManufacturer 1 ITE Technologies, Inc. iProduct 2 DVB-T TV Stick iSerial 0 If the af9015 variant uses another bcdDevice, the fix should be simple. Btw, cx231xx and dib0700 does that for some Pixelviel devices. This is how cx231xx declares his device (bcd 40.00 to 40.01): {USB_DEVICE_VER(USB_VID_PIXELVIEW, USB_PID_PIXELVIEW_SBTVD, 0x4000, 0x4001), .driver_info = CX231XX_BOARD_PV_PLAYTV_USB_HYBRID}, And dib0700 declares the same USB ID with bcdDevice range from 0.00 to 3f.00: { USB_DEVICE_VER(USB_VID_PIXELVIEW, USB_PID_PIXELVIEW_SBTVD, 0x000, 0x3f00) }, If the bcdDevice is identical, then the driver should find a way to check it during .probe time, and return -ENODEV if the device doesn't match. The other USB driver will handle it properly. Regards, Mauro ^ permalink raw reply [flat|nested] 13+ messages in thread

Well, then the alternative is to let both drivers to handle this USB ID, and add a code there on each of them that will check if the device is the right one, perhaps by looking at iProduct string. If the driver doesn't recognize it, it should return -ENODEV at .probe() time. The USB core will call the second driver. Regards, Mauro ^ permalink raw reply [flat|nested] 13+ messages in thread

Those strings could change from device to device. I used earlier af9015 eeprom hash (those string as coming from the eeprom) to map TerraTec dual remote controller and git bug report quite soon as it didn't worked.

Yeah, those strings can change, especially when vendors don't care enough to use a different USB ID/bcdDevice for different models. Yet, seems to be the cleaner approach, among the alternatives.

Damien, care to test? http://git.linuxtv.org/anttip/media_tree.git/shortlog/refs/heads/it9135_tuner I split tuner out from IT9135 driver and due to that AF9035 driver supports IT9135 too (difference between AF9035 and IT9135 is integrated RF-tuner). I added iManufacturer based checks for both AF9015 and AF9035 drivers regards Antti -- http://palosaari.fi/ ^ permalink raw reply [flat|nested] 13+ messages in thread

The it913x is a stable driver and has it own entity moving forward. The only thing that needs to happen is the id is added to it913x driver and if it doesn't apply drop it. Nack.

Stop speaking bullshit! It increases AF9035/AF9033 driver size marginally. I could guess total binary size of AF9035+AF9033+IT913X (IT913X == that new tuner driver) is smaller than size of your IT9135 blob. > The it913x is a stable driver and has it own entity moving forward. > > The only thing that needs to happen is the id is added to it913x driver > and if it doesn't apply drop it. > > Nack. If you remember about year back when IT9135 was mainlined I reviewed that stuff and criticized it wasn't split correctly. I also pointed out all what is needed is new RF-tuner driver as AF9035/AF9033 is just same silicon, but without a integrated tuner. You said on one mail something like it is too much different than AF9035 family, I didn't cared to start stupid yes/no discussion on that time. You don't have any technical reason to NACK it. Last time I was "discussing" with DS3000+TS2020 split with you and you were against. Same happens now. I ask you to look driver guidelines [1] and stop speaking BS, instead start fixing your own stuff and you will never end up situation like that.
