Writing multiple tag without removing USB SCL3711

Hello,

I'm implementing a new system to write NDEF message on tag using nfcpy. But I discovered that I have to disconnect my USB Reader every time I run the programm shown in example.
I try to implement properly the close function but still no way to do without disconnecting/reconnecting.

I precise that with libnfc I don't have the problem.
Is someone able to help me?

Thanks in advance
