Hello all
I'm trying to setup EGalax Touchscreen. The controller-ic is an etr-4000
usb.
I patched the Kernel described in "eGTouch Linux Programming Guide v2.5c". (
http://home.eeti.com.tw/web20/eGalaxTouchDriver/linuxDriver.htm)
In dmesg output the controller is listet, but there is no /dev/uinput and
no /dev/hidrawX devicefile.
Device isn't also listet under /proc/bus/input/devices.
What I have to do to get the touchscreen running?
Any help will be welcome.
Best regards
Christian

This is not really a buildroot-related question, linux-input at vger.kernel.org
would be more appropriate.
Still, some ideas:
- I never heard of /dev/uinput or /dev/hidraw. Input devices can usually be
found in /dev/input/. Perhaps you need udev rules to create /dev/uinput or
/dev/hidraw?
- Look in /sys/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0/input/input6
(and 7, 8, 9, 10); it should have an eventXX directory containing a 'dev' file.
That file contains the major:minor number of the (character) device node for
the input event device. You should have a /dev/input/eventXX device node
with the same numbers. That's the device you need.
For future posts, please
- mention the buildroot and kernel versions you use;
- post a defconfig instead of a a full config;
- post text attachments with disposition:inline so people can quote them.
Good luck!
Regards,
Arnout

In dmesg thre is:
[ 1.796470] input: eGalax Inc. USB TouchController as
/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0/input/input6
[ 1.803340] input: eGalax Inc. USB TouchController as
/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0/input/input7
[ 1.810447] input: eGalax Inc. USB TouchController as
/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0/input/input8
[ 1.817904] input: eGalax Inc. USB TouchController as

/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0/input/input10
so seems your driver works. Do you have udev (other dev management) installed?

Or eGalaxy support for their non-upstream driver.

uinput is the interface for injecting input events into the kernel
(E.G. for userspace input drivers), and hidraw is the interface
to communicate with non-input devices (ab)using the hid protocol.

Indeed.
