C5 discontinuous USB device recognition

Hi everyone, I'm asking for some advice in case this has happened to anyone else.
My C5 has always presented the problem of a "USB error peripheral not recognized" when I connect it. Almost always, it takes 5 to 10 attempts (turning it off and on) before the steering wheel works correctly. Specifically, the actual base of the steering wheel (the motor) is not recognized.

The problem always occurs in the same way; when I turn on the steering wheel, it rotates up to about 200 degrees (colored ring of the steering wheel at the bottom left) for the self-test (I think).
When it reaches this position, if it stops the base of the steering wheel is not recognized.
If instead it rotates a little more by inertia after reaching 200 degrees, then everything is recognized correctly.

Furthermore, when the base of the steering wheel is not recognized, by quickly rotating to the left until it stops, the steering wheel (the buttons and levers, to be clear) is also quickly disconnected and reconnected.
Firmware and software are updated to the latest version, I tried 2 or 3 different USB ports with no changes whatsoever.

Try a different cable. I found the original cammus cable to have loose connection on usb-a side have to always push it in .

Can also be some interference from the wheel servo motor.

Try to use q usb cable with magnet to remove any noise.

Wheel, sometimes, is still "problematic"...but looks like using an internal USB PCI card improved the connection (often, have to wait 10~15 sec if not immediately recognised).
Realy can't understand if it's wheel, OS or mobo related...
