The batch sold in 2010 called VG2010 ID 1d19:6105 has a chipsets AF9035 and Micronas AVF 49108A1. The chipset support for AF9035 ID 1d19:6105 has to be enabled in the kernel modules. The kernel driver has to be amended to support the ID 1d19:6105.

Trying to make it Work

The 3.11.10 linux kernel supports the AF9035 chipset. The device ID 1d19:6105 has to be added to the af9035.c module source of the kernel:

static const struct usb_device_id af9035_id_table[] = { . . .

   { DVB_USB_DEVICE(0x1d19, 0x6105, &af9035_props, "Dexatek Technology Ltd. Video grabber", NULL) },

. .

The module has to be recompiled as standalone module with command:

sudo make -C /usr/src/linux-headers-`uname -r` M=`pwd` modules

content of makefile:

dvb-usb-af9035-objs := af9035.o obj-$(CONFIG_DVB_USB_AF9035) += dvb-usb-af9035.o


ccflags-y += -I$(srctree)/drivers/media/dvb-core ccflags-y += -I$(srctree)/drivers/media/dvb-frontends ccflags-y += -I$(srctree)/drivers/media/tuners ccflags-y += -I$(srctree)/drivers/media/common

The relevant header files have to be copied to the af9035.c file containing directory where the command sudo make -C /usr/src/linux-headers-`uname -r` M=`pwd` modules is launched.


Firmware

The firmware needed is dvb-usb-af9035-02.fw which needs to be put into /lib/firmware directory

Drivers

See AF9035 devices.

Test System

The device is connected to a multicore Intel X86_64 system.

> uname -a
Linux Hostname 3.11.0-19-generic #33-Ubuntu SMP Tue Mar 11 18:48:32 UTC 2014 i686 i686 i686 GNU/Linux

Kernel Output

So far the kernel after sudo modprobe dvb-usb-af9035 and connecting the device fails to load the driver.
Investigation why it fails to load is on-going...

Kernel Modules

TBD

Remote Control Support

There is no remote control.

Snapshot Control Support

The housing is equipped with an push bottom to initiate a video snapshot. Operating of this shows no effect in VLC application nor /var/log/messages.
