Hmm, I was sure I never sent the email (squirrelmail did someting weird)
- sorry for the unfinished question. Anyway the answer is perfect :-)
Is that "poking" acceptable and are we going to add OLED support as
well? I'm thinking about a simple "select & load" of pre-prepared icons
for the begining. I presume gnome-settings-deamon is OK with root-only
access?
A next question: when I submitted first version of LED-over-bluetooth
for Intuos4 [1] Jiri suggested using LEDS_CLASS [2]. I submitted another
patch using LEDS_CLASS and the patch has been accepted. Patch [1]
follows the USB driver, patch [3] uses LEDS_CLASS.
So, for now we're going to have 2 different ways of handling the same
LEDs on the same device - one for USB, one for BT. My personal opinion
is that LEDS_CLASS is the right way (tm). Can we talk about changing it
in USB driver before it's too late (read: to many userland apps depend
on it)?
The same thing will apply for OLEDS, but we'll need some sysfs entries
anyway for uploading the icons anyway - I don't think LEDS_CLASS are
ready to handle it.
