Hello Mauro,

Thanks for your help.
Found your patch:

http://permalink.gmane.org/gmane.linux.drivers.video-input-infrastructure/22814

You're right, a more careful research returned
--
   - Product: PixelView PlayTV USB Hybrid

   - Part Number: PV-B308U(FRTN)-F

   - TDA18271 (NXP Hybrid Tuner), 86A20S (Fujitsu ISDB-T demodulator),
   CX23102 (CNXT AV Decoder - 10bit), USB Bridge
--
   - Product: PixelView PlayTV USB SBTVD Full-Seg

   - Part Number: PV-D231U(RN)-F

   - Chipset: DIB8076
--
Even if they share the same ID(from lsusb), chipsets are different.
This is really troublesome :(
But, the driver for CX23102 does exist in kernel.So, I was
thinkingIs there a way to force kernel to recognize the device
PixelView PlayTV USB Hybrid as anyother who uses the same chipset,
like Conexant Hybrid TV - RDE250?

Shouldn't it work? At least as a regular tv(analog)this way the
money I spent wouldn't be for nothing.

I don't know if this helps but I found this too(for fujitsu chipset,
his full name seems to be MB86A20S):

Do you think it's possible?
Thank you again for your help and patch :)

I realize now that I was kind of fast foward :) So nice to meet you all.
I hope someday, I'm able to help you guys.
Let me give you some more data from the device, although is not
directly related to my questions.

The two devices:

http://www.pixelview.com.br/play_tv_usb_sbtvd_fullseg.asp (works already)

http://www.pixelview.com.br/playtv_usb_hybrid.asp (I'm trying to get it to work)


The two boards even seems to be the same(lsusb output is the same from the two):

(from #lsusb)
Bus 001 Device 005: ID 1554:5010 Prolink Microsystems Corp.

(from dmesg)
[10994.296447] dvb-usb: found a 'Prolink Pixelview SBTVD' in cold
state, will try to load a firmware
[10994.296461] usb 1-3: firmware: requesting dvb-usb-dib0700-1.20.fw
[10994.354616] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw'
[10994.354639] dib0700: firmware download failed at 7 with -22

So, the problem to me seems to be only the firmware.
I've upload the file (merlinD.rom) to here.

http://www.2shared.com/file/URb2IeUi/merlinD.html

If anyone care to take a look.

Best wishes and many thanks for any help,

Rafael Vieira - programmer and student.

Hello and question about firmwares

2010-09-16 Thread ✎Ʀafael Vieira♦ 
Hy there,
My name is Rafael Vieira. Sorry, if I say something stupid, but let me
share with you my point of view, and you can correct me at anytime.
I have a USB PixelView SBTVD Hybrid device and it seems to me that the
only thing that keeps it from working is its firmware. Since there is
a younger brother from this board
http://dougsland.livejournal.com/103169.html that works already. I
found a rom(merlinD.rom that I can send it to the list, if you want),
from the CD of the device, that I suspect is its firmware.
Yes, I've heard of usbsnoop, but my question is, if I have the
firmware(If I'm right), can't I just rename it? Or do some operation
directly on the firmware? Do I really need to use usbsnoop? (I didn't
wan't to install windows to do this, honestly)


Thanks,

Rafael Vieira - programmer and student.
