Why is this #if in here?  Just always do it, how could it not be
defined?

User might disable the driver and CONFIG_INPUT_EBEAM_USB will not be
set. But I agree, since the device is unusable with generic HID driver
there is no point in doing this conditionally.

There's a closed-source user-space stack (libusb based daemon + xorg driver
+ wine apps) provided for some distro (Ubuntu 10.04, works on mandriva 2010,
maybe others but break on recent xorg).

I don't know exactly what to do : i don't want to break hypothetical support,
even proprietary.
Leaving the choice at kernel compile time seems to be safer, no ?

If they are using libusb that means that they use userspace solution and
do not require HID or any other in-kernel driver. They should still be
able to claim the port even if your driver is in use.

Thanks.
