A number of fliers have expressed problems with joystick and controller IDs being changed by software or OS updates.
There is a handy utility for assigning a specific ID # to each USB based controller.
It's called PJP's JoyIDs at http://pjp-s-joyids....r.com/versions/
My apologies -- I do not recommend the link above!
It's a very confusing download site and essentially wants your email address to put on their advertising list.
There are multiple links that seem to offer a download of JoyIDs but get you nowhere - just more links to other software they are hawking.
Most annoying! That wasn't my experience when I downloaded the JoyIDs executable some years ago.
The version that I have identifies itself as release 1.a
It's a 2Kb file and it's always passed my anti-virus and security scans (I use Trend Micro).
If you want the program, send me a message and I can post it on the JG1 TeamSpeak file browser.
Note: The JoyIDs.exe can assign ID numbers such #1, #2 and so on and lets you swap the ID numbers. See the screenshot below.

However, applications such as ROF see the controller IDs starting at 0 (zero).
In JoyIDs, my SideWinder MS-FFB2 joystick is ID# 1, but ROF reads this as ID# 0, my Saitek joystick as ID# 1 and my rudder pedals as ID# 2.
(I have 2 joysticks as the Saitek has a split-throttle and up to 28 separate button assignments + hat-switch)
The main utility of the program is that it allows you to put your controller IDs in the proper order.
Hopefully, this means you do not have to re-key all the axis and button assignments for a previously working game.
