[PATCH] hid-chicony: Add support for another ASUS Zen AiO keyboard

[Daniel Drake]

Add support for media keys on the keyboard that comes with the
Asus V221ID and ZN241IC All In One computers.

The keys to support here are WLAN, BRIGHTNESSDOWN and BRIGHTNESSUP.

This device is not visibly branded as Chicony, and the USB Vendor ID
suggests that it is a JESS device. However this seems like the right place
to put it: the usage codes are identical to the currently supported
devices, and this driver already supports the ASUS AIO keyboard AK1D.

Except that the AK1D is branded as Chicony. So I think it will confuse
users to ask them to load hid-chicony on a Asus keyboard branded as
JESS.

How about adding this one to hid-asus directly (with maybe a guard
against either the PID or a quirk for it)?

Cheers,
Benjamin

Hi Benjamin,

I see this was applied by Jiri before I had a chance to update it
based on your feedback.

Indeed the new keyboard added here is not branded as Chicony nor Jess,
but only as Asus.

We additionally now have another keyboard that needs the same key
handling, again only branded as Asus, but this time the USB ID is
0x062a:0x5110 suggesting manufacturer TURBOX.

I am assuming you'd prefer that we have both of these keyboards
handled by hid-asus instead of hid-chicony even that would duplicate a
bit of code. But is it really necessary to quirk it based on PID,
can't we just check for (usage->hid & HID_USAGE_PAGE) ==
HID_UP_MSVENDOR like hid-chicony does?

Thanks
Daniel

I got a bit lost about what is branded in which way ... but if you figure 
out a better driver that should be binding to the device in order to make 
the user experience better, just please send me a followup patch that'd 
move things around.

I'm going to assume that following hid-chicony here (just check the
usage page) is enough.

What I'm now curious about, looking closer, is whether we should move
the original hid-chicony Asus AK1D support to hid-asus too. You
mentioned that this keyboard is physically branded as Chicony, but are
you sure? This is not mentioned in the commit message, nor in the
original bug link, nor in the patch submission discussion.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1027789
http://www.spinics.net/lists/linux-input/msg21670.html

And google image search brings up results for both the top and bottom
of this keyboard, and no sign of any Chicony branding.
https://www.google.com/search?q=asus+AK1D&source=lnms&tbm=isch

So should I move AK1D support to hid-asus too, to match the physical branding?

Thanks
Daniel
