Christoph has made an excellent comment

Now I'm thinking about defining a "USB_DEVICE" macro for the daemons/
drivers, like:
#define USB_DEVICE(VendorID, ProductID) VendorID,ProductID

so that the USB IDs extraction routine can work for *all* existing IDs...

The only thing needed now is the script (shell or perl) that actually
do this extraction.
I see 3 routines:
* the first extract all IDs and create a [vid,pid] table,
* the 2nd will later be used to generate the udev helper. This point
needs the result of another subproject (the config helper), and will
allow to autoconfigure USB remotes,
* the 3rd generate the hal file using the following template:
- header
<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
 <device>
  <match key="info.bus" string="usb_device">
- for each [vid,pid] entry
   <!-- $comment -->
   <match key="usb_device.vendor_id" int="$VendorID">
    <match key="usb_device.product_id" int="$ProductID">
     <merge key="info.category" type="string">input</merge>
     <append key="info.capabilities" type="strlist">input</append>
     <append key="info.capabilities"
type="strlist">input.remote_control</append>
    </match>
   </match>
  </match>
- footer
 </device>
</deviceinfo>


Any volunteer?

I'll check on my side to produce the patch to "standardize" lirc driver...
