我正在为三星galaxy tab 10.1和NFC阅读器(ACR 122U)usb 开发android应用程序
当我插入usb(qith usb适配器套件sansung)并在根模式下运行dmesg时,我给出了以下错误:
usb usb2: New usb device found, idVendor 1d6b idProduct=0002
usb usb2: New Usb device String:Mfr=3 Product=2 SerialNumber=1

你们能帮我吗?
我想司机不在场。。。我该怎么办?
感谢
可能想在这里检查一下,因为这个问题似乎已经得到了回答。简言之平板电脑上的安卓操作系统不包含(没有内置)NFC驱动程序。你可能会用USB识别设备,但android内核不知道如何识别控制硬件本身。
