A lot (if not most) of NFC readers are usb/CCID. libnfc supports those using their "pcsc" driver. The current gentoo package has a pcsc-lite USE flag, but it only adds support for acr122_pcsc. I can test using a Feitan 502-dual, and using current package, i got nothing with nfc-list. The official documentation explains how the 'pcsc' driver should be configured: https://github.com/nfc-tools/libnfc#feitian-br500-and-r502 I patched (locally) the ebuild this way: - use pcsc-lite && drivers+=",acr122_pcsc" + use pcsc-lite && drivers+=",acr122_pcsc,pcsc" And now it works: orzel% nfc-list nfc-list uses libnfc 1.8.0 NFC device: Feitian R502 [R502 Contactless Reader] (BAA25E980100005D) 00 00 opened NFC device: Feitian R502 [R502 SAM1 Reader] (BAA25E980100005D) 01 00 opened NFC device: Feitian R502 [R502 Contact Reader] (BAA25E980100005D) 02 00 opened Can you include this change ?
While at it, there's a file "libnfc-1.8.0/libnfc.conf.sample" that should probably be installed as well. Maybe even as a default /etc/nfc/libnfc.conf It's all explained on: https://github.com/nfc-tools/libnfc/blob/master/README.md#configuration
