Subject: HID: Dead ./debug/hid/xxx/events
Date: Wed, 16 Nov 2011 10:50:30 +0100	[thread overview]
Message-ID: <20111116095030.GC3335@slate> (raw)

Hello everyone,

the context for this problem is getting the eGalax USB Touchscreen, ID
056a:0090, to work as such, as it is discussed on the linuxwacom-devel
list (see [1]).

Quickly summarized:

Adding the device as USB_DEVICE_ID_DWAV_EGALAX_MULTITOUCH5, in line with
the ..._MULTITOUCH[1-4], succeeds in thus far, as that it appears as a
HID Touchscreen. However, as of 3.1.x, clicking, id est touching "jams"
as in the click is never released.

Updating to 3.2.x-torvalds' kernel should have resolved that jamming,
but instead no clicks or releases are recognized at all.

The real problem with debugging that, though, is that

/sys/kernel/debug/hid/<eGalax>/events

remains dead, in any kernel, 3.1.x-gentoo, 3.1.x-vanilla and
3.2.x-torvalds alike.

I hope that you may have an idea as for any of the problems, especially
why there appears no output on the ./events node (the according node for
my keyboard reports events just fine).

Pasted is .config [2] for 3.2.x-torvalds and ./hid/<eGalax>/rdesc [3] on
3.2.x-torvalds.
