Support device 054c:1fc9 Sony Corp. NFC-PRO Reader

[albfan]

I buy a cheap reader:

https://es.aliexpress.com/item/1005005158397333.html?channel=twinner

and works correctly on windows with this software:

$ lsusb -d 054c:
Bus 001 Device 057: ID 054c:1fc9 Sony Corp. NFC-PRO Reader

I suppose is a clone, so not sure if that can be added. Just tried this quick patch:

Is there any guide to support new devices? I can test and provide feedback

I can even reverse engineering hid it if needed

Inside there's a

FM17550 chip documented here:

https://www.aliexpress.com/item/1005002458504365.html

1.1 Product introduction

FM17550 is a highly integrated non-contact communication chip that works at 13.56MHz and supports the following 4 different working modes.

Supports reader mode that complies with ISO/IEC 14443 TypeA protocol and Felica protocol

Support the reader mode conforming to ISO/IEC 14443 TypeB

Supports card simulation working mode that conforms to ISO/IEC 14443A protocol and Felica protocol

Support NFC working mode that complies with NFCIP-1 protocol

At the same time, it provides a low-power external card detection function, which is convenient for battery-powered, low-power operation, and requires real-time processing of external card reader devices that enter the radio frequency field at any time.

FM17550 has the characteristics of low voltage, low power consumption, strong drive capability, multi-interface support, and multi-protocol support. It is suitable for low-power, low-voltage, low-cost non-contact reader applications and NFC devices compatible with the NFC protocol.

Great! Provide a PR with commits to support it and ask users that reply here and at https://github.com/nfcpy/nfcpy/issues/226 to help you to debug/test it.

[albfan]

Any tips to implement its features? Not sure where to start

[dl3daz]

FM17550 could be a clone of MFRC522. When I apply albfan's patch, I get the same error as he does. kern.log has a line "kernel: [96739.964705] usb 4-1: usbfs: interface 0 claimed by usbhid while 'nfc-list' sets config #1". After "rmmod usbhid" nfc-list says

error   libnfc.driver.pn53x_usb Unable to write to USB (No such file or directory)
nfc-list: ERROR: Unable to open NFC device: pn53x_usb:004:033

I am not familiar with USB...
