Problem with mouse: No such device

[guillaumesmo]

Hi,

I have successfully cross-compiled Qt5 RC1 for the Raspberry Pi and succeeded to load an GUI application onto the linux framebuffer. The keyboard is handled correctly, not the mouse.

This error is repeated forever in the console : Could not read from input device: No such device

I have found a source file (plugins/generic/linuxinput/qlinuxinput.cpp) containing that error string, but I don't understand why it fails to read "/dev/input/event0" (except if a &specification is provided, I don't know where to check/change that)

cat /dev/input/mouse1 | hexdump
0000000 ff18 3800 fefe e838 38f5 f9f3 ec38 38fb
0000010 fef3 e738 38fb fcf0 e038 18fa 00ec d618
0000020 1800 05df f118 1804 08eb f918 1805 06f6
0000030 fe18 1802 03ff 0008 0805 0300 0008 080e

cat /dev/input/event0 | hexdump
-> nothing

I tried playing with QWS_MOUSE_PROTO, without results.

Is there someone who can save me here ?

Thanks !
