Soundgraph Finguer Vue 706 - evdev is not grabbing the device

[Thomas Weissel]

The device is recognized as mouse, added as
XINPUT: Adding extended input device "SoundGraph,Inc.--- SoundGraph.Inc" (type: MOUSE, id 10)
and then ignored.

it seems that there is only a small missing link to make it work properly

sudo cat /dev/hidraw4
2�V��2�Q�▒p2�Gg�o2�B��q2�Ap�s2�F�r2�F�r2�F�r2�F�s2�F��r2�I�▒r2�M��2�T��▒s2�

As you can see the device input is coming through.. if i cut /dev/hidraw4 and touch the screen you see something like the line above...

FingerVU is an USB composite device. This composite device consists of HID keyboard device, HID mouse device and HID compliant device. HID keyboard/mouse driver are used for IR input from remote control. The touch data is transferred through HID compliant device driver. If you'd like to get data from FingerVU touch panel, you might need to check this device.

I already tried to make it work it 2010 and spend several hours/days on it .. in this thread is everything else i tried

it's probably just a small change in usbtouchscreen module so that 15C2:3480 device is catched and configured..
unfortunately i have no idea of driver development..

this guy managed to add something to the usbtouchscreen module to get another version of the fingervue touchscreen working.
his source doesn't compile under 15.10 :(
