The SCAN_SetReaderParams Error occured when using SMDK (SymbolMobility Development Kit)1.5 for .NET

Fuc
hi experts,

We are using the Symbol MC9090G scanners, and use the symbol SMDK 1.5
for .NET to develop the WinCE form application, the tools we are using
is VS2005 professional and C#.

We are using Symbol.Barcode namespace class to read barcode and do
some logic etc. the code just like:

Symbol.Barcode.Reader _MyReader = new Reader();
....
_myReader.Actions.Enable();
....
_myReader.readNotify += (Some EventHanlder)
....
_myreader.Actions.Read();

the code above is very similar with the SMDK 1.5 sample
CS_ScanSample1. all is ok on one scanner, but, on the other scanner
it always prompt the error:
"Error
<AppName>
OperationFailureException
SCAN_SetReaderParams
At
Symbol.Barcode.ReaderParams.SetReaderParams()
At Symbol.Barcode.Actions.Read()
At <AppName>.sunWMSCycleCountDirectives.selScanLocati on()
At System.Windows.Forms.Control.OnGotFocus()
At System.Windows.Forms.Control.WnProc()
At System.Windows.Forms.Control_InternalWnProc()
At Microsoft.AGL.Forms.WL.SetFocus()
At System.Windows.Forms.Control.Focus()
At <AppName>.sunWSCycleCountDirectives.selAsile_Modif ied()
At System.Windows.Forms.ListControl.OnSelectedValueCh anged()
At System.Windows.forms.ListControl.OnSelectedIndexCh anged()
At System.Windows.Forms.ComboBox.onSelectedIndexChang ed() "

I don't know why this come up. there is some differences between two
scanners.
the good one 's OS Version: 05.01.0476, OEM name: SYMBOL MC9090G, OEM
Version: 01.35.0002, IPL version:01.43.441; and other one's OS
version: 05.00.000 , OEM Version:01.20.0000, IPL Version:01.42.440;

I'm not sure if this system little difference make it.

Any help is highly appreciated!! and sorry for some rusty english.

Thanks,
Andy
