如何根据USB端口位置连接智能卡读卡器？

Question

I'm currently doing some research and testing on multiple smart card reader identification to determine which reader is connected to which USB port.

Lets say that I plug in Reader A into USB port 1. By invoking SCardListReaders function, I retrieve the following friendly name:

• ACS ACR1281 1S Dual Reader PICC 0

Then I plug in another reader (Reader B) into USB port 2. Now I have 2 readers connected to the same PC. Invoking SCardListReaders will give me:

• ACS ACR1281 1S Dual Reader PICC 0
• ACS ACR1281 1S Dual Reader PICC 1

I'm aware of how these names are generated ( How are PCSC smart card reader 'friendly names' constructed? ) and I know that plugging in the readers in different sequence (plug in Reader B first then Reader A) will change the SCARD_ATTR_DEVICE_UNIT thus affecting the friendly names.

Based on the above scenario, how can I ensure that the PC will always automatically connect to PICC reader in USB port 1 regardless of its friendly name?

Any help will be much appreciated. Thank you.
