Hi all,

I have a Geniatech UTV3 usb tv box that didn't worked on linux.

After taking the device apart, I found following components
* FM24C02 -> EEPROM
* EM2860 -> USB Video Capture Device
* SAA7113H -> Video input processor
* TOA9801 -> Demodulator and FM-PLL detector (for sound)
* HCF4052 -> Analog multiplexer (for switching sound between TV and AV)
* TNF8337-DFD -> TV tuner/reciever

After I insmoded the em28xx,the device was detected as the EM2860_BOARD_TYPHOON_DVD_MAKER?? I figured out the "TYPHOON_DVD_MAKER" and my Geniatech UTV3 must have the same Vendor/Product ID.

#lsusb
Bus 004 Device 012: ID eb1a:2860 eMPIA Technology, Inc.

I guess somebody has to change the detection system to handle different devices with the same Vendor/Product ID.

I had to make some modifications to the em28xx driver in order to get the Geniatech device working. I changed the EM2860_BOARD_TYPHOON_DVD_MAKER struct in em28xx-cards.c to the following:

[EM2860_BOARD_TYPHOON_DVD_MAKER] = {
       .name             = "Geniatech UTV3",
       .vchannels      = 2,
       .tuner_type    = TUNER_TNF_5335MF,
       .has_tuner      = 1,
       .norm              = V4L2_STD_PAL_BG,
       .decoder         = EM28XX_SAA7113,
       .dev_modes    = EM28XX_VIDEO,
       .input             = {{
           .type     = EM28XX_VMUX_TELEVISION,
           .vmux    = SAA7115_COMPOSITE2,
           .amux    = 0,
       },{
           .type     = EM28XX_VMUX_COMPOSITE1,
           .vmux    = SAA7115_COMPOSITE0,
           .amux    = 1,
       }},
       .tvnorms    = {{
               .name = "PAL-BG",
               .id = V4L2_STD_PAL_BG,
           },{
               .name = "PAL-DK",
               .id = V4L2_STD_PAL_DK,
           },{
               .name = "PAL-I",
               .id = V4L2_STD_PAL_I,
           },{
               .name = "PAL-M",
               .id = V4L2_STD_PAL_M,
           },{
               .name = "NTSC",
               .id = V4L2_STD_NTSC,
       }},
},

I know this isn't a 'proper' solution, but it's fine for me.

The tuner isn't actually a TVF58t5-MFF, it is an SN761678. (the SN761678 is located inside the TNF8337-DFD)

After compiling and reloading the em28xx driver, the geniatech device was properly detected. #dmesg

[32986.040748] usbcore: registered new interface driver em28xx

With this new configuration I'm able to watch TV using xawtv. Only the sound wasn't working.

The sound isn't available through the usb connection(like the driver said), but it goes out by a audio jack connector.

After a while a discovered that the em28xx didn't controlled the multiplexer (HCF4052).
The multiplexer is used to switch between the sound of the TV and the sound of the AV.
In oder to get sound out of the audio connector the following configuration has to applied to the multiplexer

        A         B
TV:    1          0
AV:    0          0

Other combinations give no output.

The multiplexer is connected by pin 10(A) and 9(B) to the em2860 by pin 27(PIO0) and 28(PIO1). During the use of the em28xx driver the PIO0 and PIO1 are 3.3V, thus resulting no sound. The PIO's of the em2860 are probably configured as input, and are pulled up to 3.3V

As a temporarily solution I lifted pin 9(B) from the multiplexer and connected it to GND. This way I can listen and watch to the TV.

I hope that this contribution can help to the further development of the em28xx driver.

Greets,
Eli

I guess somebody has to change the detection system to handle different devices with the same Vendor/Product ID.

FYI: the em28xx driver does have the ability to handle different devices with the same Vendor/Product ID. See the em28xx_i2c_hash and em28xx_eeprom_hash in em28xx_cards.c, used by the em28xx_hint_board() function.

To use it, remove your entry from em28xx-cards.c, connect the device, and the i2c hash will be shown in the dmesg output. Then just add it to the list.

Regards,

Devin

Hi all,

I have a Geniatech UTV3 usb tv box that didn't worked on linux.

After taking the device apart, I found following components
* FM24C02 -> EEPROM
* EM2860 -> USB Video Capture Device
* SAA7113H -> Video input processor
* TOA9801 -> Demodulator and FM-PLL detector (for sound)
* HCF4052 -> Analog multiplexer (for switching sound between TV and AV)
* TNF8337-DFD -> TV tuner/reciever

After I insmoded the em28xx,the device was detected as the EM2860_BOARD_TYPHOON_DVD_MAKER??
I figured out the "TYPHOON_DVD_MAKER" and my Geniatech UTV3 must have the same Vendor/Product ID.

#lsusb
Bus 004 Device 012: ID eb1a:2860 eMPIA Technology, Inc.

I guess somebody has to change the detection system to handle different devices with the same Vendor/Product ID.

I had to make some modifications to the em28xx driver in order to get the Geniatech device working.
I changed the EM2860_BOARD_TYPHOON_DVD_MAKER struct in em28xx-cards.c to the following:

[EM2860_BOARD_TYPHOON_DVD_MAKER] = {
      .name             = "Geniatech UTV3",
      .vchannels      = 2,
      .tuner_type    = TUNER_TNF_5335MF,
      .has_tuner      = 1,
      .norm              = V4L2_STD_PAL_BG,
      .decoder         = EM28XX_SAA7113,
      .dev_modes    = EM28XX_VIDEO,
      .input             = {{
          .type     = EM28XX_VMUX_TELEVISION,
          .vmux    = SAA7115_COMPOSITE2,
          .amux    = 0,
      },{
          .type     = EM28XX_VMUX_COMPOSITE1,
          .vmux    = SAA7115_COMPOSITE0,
          .amux    = 1,
      }},
      .tvnorms    = {{
              .name = "PAL-BG",
              .id = V4L2_STD_PAL_BG,
          },{
              .name = "PAL-DK",
              .id = V4L2_STD_PAL_DK,
          },{
              .name = "PAL-I",
              .id = V4L2_STD_PAL_I,
          },{
              .name = "PAL-M",
              .id = V4L2_STD_PAL_M,
          },{
              .name = "NTSC",
              .id = V4L2_STD_NTSC,
      }},
},

I know this isn't a 'proper' solution, but it's fine for me.

The tuner isn't actually a TVF58t5-MFF, it is an SN761678. (the SN761678 is located inside the TNF8337-DFD)

After compiling and reloading the em28xx driver, the geniatech device was properly detected.

[32986.040748] usbcore: registered new interface driver em28xx

With this new configuration I'm able to watch TV using xawtv. Only the sound wasn't working.

The sound isn't available through the usb connection(like the driver said), but it goes out by a audio jack connector.

After a while a discovered that the em28xx didn't controlled the multiplexer (HCF4052).
The multiplexer is used to switch between the sound of the TV and the sound of the AV.
In oder to get sound out of the audio connector the following configuration has to applied to the multiplexer
A B

TV:    1          0
AV:    0          0

Other combinations give no output.

The multiplexer is connected by pin 10(A) and 9(B) to the em2860 by pin 27(PIO0) and 28(PIO1).
During the use of the em28xx driver the PIO0 and PIO1 are 3.3V, thus resulting no sound.
The PIO's of the em2860 are probably configured as input, and are pulled up to 3.3V

Quoted 8 lines

As a temporarily solution I lifted pin 9(B) from the multiplexer and connected it to GND.
This way I can listen and watch to the TV.

I hope that this contribution can help to the further development of the em28xx driver.

can you submit the usbview output? depends what this device is set to in order to get
audio through the digital link.

Markus

Markus,

The sound goes only by the external audio jack, even in "windows".
In order to play audio through your PC speakers, the device comes with an extra cable. Witch you should connect to the line-in of the PC's audio card.

Anyway, here is the usbview output.
