xpe Smart Card Resource Manager

Hello,
i want a smart card reader working on xpe. so i installed all needed driver
and tried afterwards to start the SCardSrv (Smart Card Resource Manager)
local service - the following message was displayed:

Could not start Smart Card Resource Manager service on Local Computer
Error 1068: The dependency service or group failed to start.

on the xpe system no dependencys are shown to me. on a xp pro system a
dependency to the plug & play service is shown to me.

so my main problem is that the needed service will not run on the xpe - have
any one a idea?!
thanks
