2.4.19, USB_HID only works compiled in, not as module

Not so. USB Mouse works just fine here on 2.4.19.

$ lsmod
....
mousedev                4352   1
hid                    14112   0 (unused)
input                   3328   0 [mousedev hid]
....

CONFIG_INPUT=m
# CONFIG_INPUT_KEYBDEV is not set
CONFIG_INPUT_MOUSEDEV=m
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1280
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=1024

CONFIG_USB_HID=m
CONFIG_USB_HIDINPUT=y
# CONFIG_USB_HIDDEV is not set

'cat /dev/input/mice' (a cat and mouse game?) gives output as well.

So there appears to be no generic 2.4.19 problem.

Hm, seems so. The relevant options I used are:

CONFIG_INPUT=y
# CONFIG_INPUT_KEYBDEV is not set
CONFIG_INPUT_MOUSEDEV=m
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768
CONFIG_INPUT_JOYDEV=y
CONFIG_INPUT_EVDEV=m

CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI=y
CONFIG_USB_HID=m
CONFIG_USB_HIDINPUT=y

I don't know if it's a config problem. First I suspected CONFIG_USB_HIDINPUT could be the problem because it's new in 2.4.19. But as I see it works for you, so there shouldn't be a problem.

What other USB options do you have turned on?

What modules do you have loaded?

Vojtech: We need that /proc support for input to help with problems like this. Any chance of merging it in 2.4.20-pre?

Here's everything either modules or compiled in. Currently with the hid/mouse stuff compiled in:
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI=y
CONFIG_USB_STORAGE=m
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_VISOR=m

Mainly alsa, bttv and lm_sensors. I know, I know NVdriver. But it doesn't make any difference without loading it.
