how to identify which one is removed?

[fumac_3907466]

If I add two usb in the PC.

CCyUSBDevice*   m_pCyUSBDevice1;

CCyUSBDevice*   m_pCyUSBDevice2;

m_pCyUSBDevice1->Open(0);

m_pCyUSBDevice2->Open(1);

However, if remove one usb.

m_pCyUSBDevice1->Isopen = true;

m_pCyUSBDevice2->Isopen = true;

1. How to identify which one is remove? Why those are all opened?

2. If the removed one is inserted, how to open it?  I don't know which one?

3. Could you help to descripe the solution by codes more detail?

Hello,

Please refer to Example#1 under the CCyUSBDevice class definition of the CyAPI.PDF (Present as part of the FX3 SDK) document for details on handling the PnP events.
