Brazilian HDTV device

Brazilian HDTV device

[Moacyr Prado]

Hi, I have a board with empia chipset. The em28xx driver not load, 
because the device ID is not listed on source(cards.c, I guess). 

Following bellow 
have some infos from board:
lsusb:
Bus 001 Device 004: ID 1b80:e755 Afatech

Opening the device, shows this ic:

empia em2888 d351c-195 727-00ag (em28xx)
nxp saa7136e/1/g SI5296.1 22 ZSD08411
NXP TDA 18271??C2 HDC2? (tda18271)
F JAPAN mb86a20s 0937 M01 E1 (mb86a20s)

but... dmesg shows:

[18373.454136] usb 6-1: USB disconnect, address 2
[18376.744074] usb 2-1: new high speed USB device using ehci_hcd and address 9

[18376.860300] usb 2-1: Product: USB 2885 Device
[18376.860306] usb 2-1: SerialNumber: 1


Could The em28xx module (writing some code for me)handle this device?

Thanks,
Moa

But is not working yet, DVB scan always fail. It must be gpio settings. I got a sniffer data from win7 driver. Anybody has a tip to discover gpio settigs from data sniffed?  

Thanks 
Moa.

Moacyr,

Take a look at the v4l-utils tree. There are some parsers there for some common sniffer
formats, at the utils dirs, and a parser for em28xx format. You may eventually need to 
write a new parser, if your sniffer has a different format.

Of course, you can just try to search for the changes at the GPIO registers, but doing
it manually may be very time-consuming.

Cheers,
Mauro
