Smartcard reader naming

I have two readers (HID OMNIKEY 5321) in system (every reader performs a different function)

In my program is set up that

but sometimes (without rebooting, perhaps lost contact)

and the program does not do what users need. I use SCardGetStatusChange (requires the name of the reader) in WinScard.dll

What to do? Is there a way to change the name of the reader (firmware, drivers...)? Is it possible to use the serial number of the reader?

I also looked, but no result Smartcard reader naming: when removing any reader, the name of the rest changes How are PCSC smart card reader 'friendly names' constructed?

Maybe you should focus on the smartcard inserted in / connected to the reader rather than the reader itself and use card specific information (i.e. serial number or label) to choose the correct reader.
