Motorola MC65设备中的Magnetc Stripe Reader问题

Question

我在Motorola MC 65(操作系统:Windows Mobile)中遇到了Magnet Stripe Reader的问题.如果我尝试打开Reader,我会得到一个例外MSR_Open MSR_Err_OpenFailure.

码:

Symbol.MagStripe.Device MyDevice = new Symbol.MagStripe.Device(myDiv.DeviceName);
this.MyReader = new Symbol.MagStripe.Reader(MyDevice);
this.MyReader.Actions.Enable();

堆栈跟踪:

Symbol.magstripe.magstripe Marshal.open(stringsdevicename, stringsportname) at
Symbol.magstrip.actions.enable() at
Ecollect.ecscancardcf.start read()
