Hi

I recently got a used USB touchscreen and try to get it working
It looks like a eGalax type but not really is :-(

I am using kernel 2.6.28.2 but also tried the one that comes with
fedora 10 (2.6.27) When I connect the touchscreen dmesg shows

usb 2-1: new low speed USB device using uhci_hcd and address 13
usb 2-1: string descriptor 0 read error: -32

E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=5ms

I compared this output to other eGalax and discovered some differences
like that iManufactur and iProduct is not filled also
bInterfaceSubClass and bInterfaceProtocol

The kernel is not installing any input device for the touchscreen
so /proc/bus/input/devices does not show the touchscreen

To check if the thing is actually working I did a quick test on XP
and there it works.

Any chance to get this thing working?
I can test any patch maybe required and provide more information if
needed. If am wrong on this mailing list please tell me where
I should post this question.

Thanks for any help

Max

Looks like a touchscreen which is supported by a closed(?) source driver
of eGalax we have here too:
$ /sbin/modinfo tkusb.ko

You can obviously download the drivers from
<http://home.eeti.com.tw/web20/TouchKitDriver/linuxDriver.htm>.

It would be great if eGalax could be convinced to get these drivers
included in main-line ;)

Hope that helps,
Niels

Thanks for your quick reply
BUT: I have tried those driver also

I tried this "brandnew" one (but also older ones)
http://home.eeti.com.tw/web20/drivers/touch_driver/Linux/2.06.2416/TouchKit-2.06.2410-32b-k26.tar.gz
after making it compile for 2.6.28.2 :)
since there is source code delivered

If I didnt make any error I get exactly the same error
maybe I did some error in the configuration but
it loads the tkusb kernel module instead of the usbtoucscreen
(which I added to the module blacklist) when plugin the screen
so I think I did it right :)

So maybe the problem is that the kernel is just too new 
and some other changes broke the support :)
So I will try with the kernel you are using
(2.6.17-8) to make sure

For what it's worth; the version we use from eGalax is 1.0.3.1701. I
don't have the hardware here atm, so I can't test an other driver
now.

Cheers,
Niels

I tried kernel 2.6.23.17 and there the touchscreen is recognized
using the builtin usbtouchscreen driver

/proc/bus/usb/devices delivers
T:  Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=1.5 MxCh= 0
D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0eef ProdID=0001 Rev= 1.00
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr= 44mA

E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=5ms

and

/proc/bus/input/devices
I: Bus=0003 Vendor=0eef Product=0001 Version=0100
N: Name="USB Touchscreen 0eef:0001"
P: Phys=usb-0000:00:1d.0-2/input0
S: Sysfs=/class/input/input3
U: Uniq=
H: Handlers=mouse2 event3 
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=3

I also tried to blacklist the usbhid with 2.6.28.2
then it display Driver=usbtouchscreen in /proc/bus/usb/devices
but still no entry in /proc/bus/input/devices

Any ideas?

It also works with 2.6.26.8

After comparing the usbtouchscreen.c sources between the different
versions I got it working by commenting the follwoing lines

...
#ifdef CONFIG_TOUCHSCREEN_USB_EGALAX
        /* ignore the HID capable devices, handled by usbhid */
        {USB_DEVICE_HID_CLASS(0x0eef, 0x0001), .driver_info = DEVTYPE_IGNORE},
        {USB_DEVICE_HID_CLASS(0x0eef, 0x0002), .driver_info = DEVTYPE_IGNORE},
...

Now the entry in /proc/bus/input/devices is created as in the
older versions.

So it seems that usbhid is not correctly handling my type
of touchscreen if I understand the comment there correctly

Well I am really not an expert in kernel programming :-)
I found out that these lines where added based on this thread from 2008

http://kerneltrap.org/mailarchive/linux-kernel/2008/6/28/2286264/thread

So all I can do is to provide any help in testing if needed

[PATCH] usbtouchscreen: fix eGalax/ETTI HID device ignoring

Fix the eGalax/ETTI HID device ignoring by adding a match for the protocol too.
This is what the marco USB_DEVICE_HID_CLASS() was supposed to do anyways.

Devices confirmed to be real HID have the class set to HID and the protocol
set to 'mouse'.  Some have HID class but protocol set to 'none'. Those are
not HID and should be driven by usbtouchscreen.

I patched usbtouchscreen.c in my 2.6.28.2 kernel

But if I look in /proc/bus/usb/devices
the touchscreen is now managed from the usbhid driver
so usbtouchscreen is again ignoring my device

/proc/bus/input/devices is again empty and no
entry exists for the touchscreen :-(

This is the same behaviour that I had before
copying back "my patched" version and everything is
working again.

Just to make sure I understand how this should work
the entry must be there also if usbhid is managing
the touchscreen right?

BTW: dmesg contains a new line with the patched version
generic-usb: probe of 0003:0EEF:0001.0002 failed with error -32
when initializing the touchscreen

So sorry no success here

But I have to say that I got this touchscreen very cheap
second hand and maybe this is just some stupid problem
only for this device.

If your code works for all the other devices you tested
I am fine doing my change for now and you should not
waste more time on this :-)

Thanks

errm, forget the patch i sent you...it just couldn't work:
instead of the flag USB_DEVICE_ID_MATCH_INT_PROTOCOL i took
USB_DEVICE_ID_MATCH_DEV_PROTOCOL which is just wrong wrong wrong :)

Best would probably be updating the Xorg evtouch-driver. It looks like someone 
already did this. I found a site containing a quite complete description of
(hopefully the same) problem: http://zalman.ostergaard.net/touch.html

However I don't think the changes were submitted upstream as the (new) driver 
does not contain support for the other eGalax-hardware anymore.

In my view the problem is not the Linux usbtouchscreen/usbhid driver, but the
evtouch-driver. It looks like the evtouch-driver is not maintained by the
Xorg-folks, but on http://www.conan.de/touchscreen/evtouch.html (contact
added in CC).

Anyone interested in creating a patch for evtouch?

Well the problem here IMHO is the following sentence found there

without the changes in usbtouchscreen /proc/bus/input/devices does
NOT contain any entry for my touchscreen.

I think the problem cannot be fixed by any changes on the X-level
since this requires that the underlying device is present
e.g. any /dev/input/event[x] device for the touchscreen

evtouch is just one level above and is just using the device
that is provided from the kernel aka. usbtouchscreen or usbhid

At least this is how I understand the architecture :)
