Error during deployment...

Hi,
When I try to deploy a mobile application from VS2005 to my Asus MyPal A636
an error occours:
Description: "Interface not registered". File:"Device connectivity
component".
The same error occours if I try to use Visual studio remote tools.
why?
P.s. If I use an Emulator the deploy works fine. I installed ActiveSync 4.2
and windows mobile 5 sdk.
Thanks!
