Subject: RE: [PATCH] hid: usbhid: New hid quirks for Panasonic Elite
 Panaboard T-780 and T-880

Hello Jiri,

Panasonic Elite Panaboard UB-T780 is a touchscreen whiteboard. It uses projector to present PC's screen onto the board. So we need to calibrate it according to the projector's position and apply calibration data inside our driver.

There is no other driver for this device. I'm working directly for Panasonic on this driver.

Is this nice for changelog comment?

With best regards,
Anton Chikin

Could you please be more verbose in the changelog?

Is the generic HID driver not working with these devices at all? Or is the 
functionality only limited, not exploiting all the features the hardware 
provides?

Is there any other driver available for these devices?

Thanks.
