I think it is hid:

pavel@amd:/data/l/linux$ cat .config | grep MOUSE
CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768
CONFIG_INPUT_MOUSE=y
CONFIG_MOUSE_PS2=y
CONFIG_MOUSE_SERIAL=y
# CONFIG_MOUSE_INPORT is not set
# CONFIG_MOUSE_LOGIBM is not set
# CONFIG_MOUSE_PC110PAD is not set
# CONFIG_MOUSE_VSXXXAA is not set
# CONFIG_USB_IDMOUSE is not set
pavel@amd:/data/l/linux$ cat .config | grep HID
CONFIG_BT_HIDP=y
# HID Devices
CONFIG_HID=y
CONFIG_USB_HID=y
# CONFIG_USB_HIDINPUT_POWERBOOK is not set
# CONFIG_HID_FF is not set
# CONFIG_USB_HIDDEV is not set
# CONFIG_USB_PHIDGET is not set
pavel@amd:/data/l/linux$

Should I disable config_hid and try some other driver?
