我正在开发一个 javascript 库来使用 CCID 协议通过 chrome webusb API 执行智能卡操作。当我在 Linux 和 MacOS 上插入智能卡读卡器时,一切都很顺利,但是当我尝试声明接口时,我卡在了 Windows 上。我尝试以管理员身份运行 chrome,禁用 Windows 上的智能卡服务/CCID 驱动程序,以防它们声称该接口,但什么也没做。我一直收到“无法声明接口:访问被拒绝(权限不足)”消息。真的是权限问题吗?还是我不知道阻止访问的某些 Windows 服务?
编辑:我在另一台 Mac 上试过,但阅读器无法正常工作。从 CCID 驱动程序 info.plist 中删除特定的供应商 ID/产品 ID 后,我设法使其工作。所以我想同样的问题也发生在 Windows 上,CCID 驱动程序正在“阻塞”访问接口。我的选择是什么?
