Dear List,
using the current (Linux v2.6.7) hid-multitouch driver I have the problem, that
the touchscreen works fine after a fresh boot, but after a suspend the
touchscreen does not come back to live and I am asking for assistance to get
this working. As I can reproduce this problem on a standard tty device without
X (see below) I am suspecting a driver problem, but I might as well be wrong.
The device in question is the Touchscreen of a Dell Inspron Duo convertable, a
USB device with id 0eef:725e (D-WAV Scientific Co., Ltd), found and registered
as an input device by the kernel as
[ 6.931638] usb 4-1: Manufacturer: eGalax Inc.
[ 16.186272] input: eGalax Inc. USB TouchController as
/devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/input/input10
[ 16.187162] hid-multitouch 0003:0EEF:725E.0001: input,hiddev0,hidraw0: USB
HID v2.10 Pointer
[eGalax Inc. USB TouchController] on usb-0000:00:1d.2-1/input0
I have tested the behaviour with and without X11. Without X11 I was using a
standard tty and using cat on the input device.
After boot the input device gives lot of output while touching the screen,
after resume the device stays silent.
I have this problem since moving to hid-multitouch for handling this device.
I will be happy to test and supply more information. Thanks a lot for looking
into this,
Jan-Matthias Braun
