[PATCH 1/3] HID: wacom: Move Graphire raport header check.

[PATCH 1/3] HID: wacom: Move Graphire raport header check.

[Przemo Firszt]

That check is valid only for Wacom Graphire, as the device raports always
start with 0x03. Intuos4 WL high-speed raports begin with 0x04, so
the check would be filtering out valid reports.

[PATCH 2/3] HID: wacom: Add speed setting for Intuos4 WL

[Przemo Firszt]

Add option to change reporting speed for Intuos4 WL. The option is only
internal to the module, but it will be extended to allow control over sysfs,
as it is already implemented for Graphire.

[PATCH 3/3] HID: wacom: Unify speed setting

[Przemo Firszt]

This patch unifies speed setting for both supported tablets. Functionality
of "wacom_poke" (used only by Graphire) is now in "wacom_set_features".
Reporting speed for both tablets can be changed by somethinkg like:

echo 1 > /sys/class/bluetooth/hci0/hci0:1/{device No}/speed

Accepted values:
0 - low speed,
1 - high speed.

The way of changing reporting speed is the same for Graphire and Intuos4 WL.
