steering wheel keep disconnecting

Hi guys,

I recently experienced a problem never happened before.

I recently finished the assembly of a DIY steering wheel that works great, pass all the tests out of games.

Here is what happen

- When I connect the wheel everything goes OK

- When I start SimHub (before or after connecting the wheel) everything goes OK

- When I launch Iracing (if I am lucky) after few minutes the wheel LED turn white, buttons unresponsive, and the sound of repeated hardware disconnection; at that point if I try to disconnect and reconnect the wheel, it just turn white not loading the screen and repeated disconnection sound.

- When I reconnect the wheel without exiting and re-entering SimHub, keep disconnecting sound

At the moment I only tested on ACC and Iracing, and as I start the session the same issue happens.

I have tried to

- use different USB port, hub, back pc, front pc, same issue.

- disconnect all the unnecessary devices (button boxes, FX, other screens) same issue.

that doesn't happen if I run Z1 dash, so I suppose is some thing related to SimHub that doesn't go right

If I use my Wireless simucube wheel the issue doesn't happen (but that is not USB 😉 )

if I use my dash with Vocore + LED (not with that wheel) no issue.

I noted that entering the arduino section of simhub and going on my hardware, it says COM6 "unusable port (configured for commercial PID/VID)".

the hardware of the wheel is KODAI RACING GR.3S.

if anyone can help would be great

Thank you
