Right. I'm already kicked from the challenge (my bad :( ), but I still
wanted to know how this may be possible. Though, it's probably not a
good idea to talk about this as others may be doing the challenge.

Anyway, thanks for your help.

The challenge asked for userspace dynamic *loading* on hotplug which I
had done, but while I was reading LDD 3rd ed., I also wanted to get
probing to work which is done after the driver is already loaded.
That's when I found out only one driver can claim a device and wanted
to see if it were possible to change which driver binds which device
at runtime without reloading usbhid or changing the order which
modules are loaded.

Thanks,
