I've beenusing a USB Smart Card to do Internet banking since I bought my new laptop with Vista Business installed.After a second smart cardhad beeninstalled, I received error messages whenever I opened an Internet Explorer. Sick of this behavior, I uninstalled the second smart card. Since then, my first Smart Card also does not work anymore. Whenever I put in the USB stick, I receive the following error message (XML view copied from Event Viewer): - <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> - <System> <Provider Name="Microsoft-Windows-Smartcard-Server" Guid="{4FCBF664-A33A-4652-B436-9D558983D955}" EventSourceName="SCardSvr" /> <EventID Qualifiers="0">610</EventID> <Version>0</Version> <Level>2</Level> <Task>0</Task> <Opcode>0</Opcode> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2008-11-16T12:04:51.000Z" /> <EventRecordID>53258</EventRecordID> <Correlation /> <Execution ProcessID="0" ThreadID="0" /> <Channel>System</Channel> <Computer>FrankQuosdorf</Computer> <Security /> </System> - <EventData> <Data Name="Message">The request is not supported.</Data> <Data Name="Reader">Gemplus USB Key Smart Card Reader 0</Data> <Data Name="IOCTL">EJECT</Data> </EventData> </Event>I uninstalled and resinstalledthe first USB smart card - no success.Windows help was not helpful at all, and searching forums did not lead to a solution either. Is there a way to restore the USB driver?
