请大佬完善一下对ACR122U的支持

[MyHeart-lang]

PN532支持确实不错，但是对于老牌读卡器ACR122U支持却不完美，响应慢是常事。ACR122U可是以快速的读写卡为招牌~~~

请问在win10上安装了libusb，然后依然出现如下问题，楼主有办法解决吗

[lixin9311]

应该是libusb库没处理好。
windows上莫名其妙我给跑起来了，分享一下做法：

1. 用Zadig安装libusb驱动给acr122
2. 下载，并且跑这个的英文版，点检测设备，应该会报错 https://github.com/xavave/MifareOneTool-English
3. 英文版别关，跑最新的1.7.0的中文版，点检测设备，应该会听到usb设备插拔的提示音，并且监测失败。
4. 这个时候试一下英文版，应该可以读写卡了

如果有其他人试一下没问题请回复一下。

别问我怎么知道的，凑巧。
