Problems with wheel (Logitech)

Hi all. I have two problems.
I connect Logitech G27 to Unity3D. all right but… 3 wheel buttons don’t work, becouse this buttons - joystic button > 19. Unity don’t see that. (For example button 20,21 e.t.c)

2 Problem: with Logitech SDK from UnityStore. (Special to vibrations e.t.c) Have error:

DllNotFoundException: LogitechSteeringWheel
LogitechSteeringWheel.Update () (at Assets/Logitech SDK/Script Sample/LogitechSteeringWheel.cs:52)

DLL: LogitechSteeringWheel.dll in folder LogitechSDK → LIB → Wheel → x64.
I read some information about this in different forums and:

  1. I move .dll to ‘Plugins’ folder. Dont work too.
  2. I read: need copy .dll to Unity Editor folder. Dont work too.

Help me please.

Thanks in advance.
Best Regards,
Alex.

P.S: On screen some wheel tests.
P.S.S: Sorry for my english!

Do you use unity pro?

Yes. Unity 4.2.

Same here. I’m getting the following errors actually:

DllNotFoundException: LogitechSteeringWheel
LogitechSteeringWheel.Start () (at Assets/Logitech SDK/Script Sample/LogitechSteeringWheel.cs:35)
DllNotFoundException: LogitechSteeringWheel
LogitechSteeringWheel.Update () (at Assets/Logitech SDK/Script Sample/LogitechSteeringWheel.cs:52)

Have you had any luck with it lately?
