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
