Maybe there is some confusion on where the driver code and module 
parameters should go, and the purpose of unusual_devs.h, that leads to 
this unusually-worded question.

First of all, could you please explain what kind of device are you 
trying to use (if possible, with device/vendor IDs)? Is it a 
mass-storage device (such as an external disk/DVD/flash memory), or is 
it something else? If it is, then why do you need a parameter to 
unusual_devs.h ? What kind of behavior do you need to control from 
userspace? Why is none of the existing quirks useful for your device? 
Maybe what you want is to add a new quirk flag, and there is nothing 
wrong AFAIK with adding code to handle that particular flag.

If, on the other hand, your device is not a mass-storage device, then 
nothing you do to unusual_devs.h might be useful. That file is only 
relevant for mass-storage devices.

A quick description of your environment (target kernel version, 
distribution, etc) won't go amiss.
