How to change back the Joy# 174 number?

[Guido]

Hi,

I got the W10 anniversary update by surprise. And the surprise swapped the GoFlight assignments of the two GF186 (NAV<->COM) and the two GF-RP48 units.

Meanwhile I understand the basics about the USB mechanism.
But I don’t understand how and where the unit numbers displayed in FSUIPC (Joy# 174, 175,…) are linked with the USB HW Port/Hub number and/or USB addresses?  Registry?

As I am using parallel to the W10 P3D also a W7 FSX system I really would like to keep the same assignment for both sims.

How can I influence W10 to change back to the former unit order (174 <-> 175) assignments?

Many thanks for help

No, not directly -- only the order in which Windows ennumerates them when asked. I assume that's to do with it's USB scanning.

The easiest thing to do is swap the USB plugs over.
