Solution for multiple USB devices/hacks

[whammoed]

AdvanceMAME 90 has been realeased and an interesting thing in this release:

The USB devices in Linux now have always the same order in the input_map[] specifications

What has been done here is that the devices are now sorted by manufacturer and model number first and the order they are recognized second.  This is the fix for those of you who hack multiple usb game pads but they flip flop order on boot.  Of course the catch is you don't want to use the exact same game pads....need to use different models.  I submitted this feature request because I have three usb mice (optipac and tornado spinner) and one time they changed order.  Although they haven't changed order again since I plugged them in to different sections of the motherboard (I have on set of two and on set of four ports) I thought it would still be a great feature for those using a hub or with only one set of ports.   ***haven't had a chance to test it out yet, I'll report back on it later***

USB ports are always in pairs.

I thought so too, but I have a MB with 4 ports grouped together, so I thought 2 and 2 right?  However the mice did flip flop once.  Maybe it was a fluke.  Regardless it is still good if you are using a hub.
