WebUSB API保护的接口类错误 [英] WebUSB API protected interface class error

问题描述

我正在尝试将WebUSB api与Chrome 67结合使用.一个月前，以下代码可以正常工作.我不确定是否更改了某些内容或丢失了某些内容.当我尝试声明该接口时，发生了我现在得到的错误.

I'm trying to use the WebUSB api with Chrome 67. The following code was working a month ago. I'm not sure if something is changed or if I missing something. The error I'm getting now is occurring when I'm trying to claim the interface.

错误消息如下:DOMException: The requested interface implements a protected class.和An attempt to claim a USB device interface has been blocked because it implements a protected interface class.

  window.setInterval(function() {
    navigator.usb.getDevices({ filters: [{ vendorId: 0x0b67 }]
    }).then(function(devices) {
      device = devices[0];
      return device.open();
    }).then(function() {
      return device.selectConfiguration(1);
    }).then(function() {
      return device.claimInterface(0);
    }).then(function() {
      return device.transferIn(1, 6);

我找不到有关该错误的任何信息，我们将不胜感激.

I can't find any information about the error, any information would be appreciated.
