USB Subsystem Changelog

cl.usbManager.1 Change of Error Code from 202 to 201 for Calling a System API When the ohos.permission.MANAGE_USB_CONFIG Permission Is Missing

Access Level

System API

Reason for the Change

When the system API is called, the ohos.permission.MANAGE_USB_CONFIG permission must be added to the permission field in the system application configuration file. If the permission is not configured, error code 201 is returned.

Change Impact

This change is a non-compatible change.

The following is an example:

import { usbManager } from '@kit.BasicServicesKit';
import { bundleManager } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';
let devicesName: string = "1-1";
let tokenId: string = "";

  try {
    let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULT;
    bundleManager.getBundleInfoForSelf(bundleFlags).then((bundleInfo) => {
      console.info('testTag', 'getBundleInfoForSelf successfully. Data: %{public}s', JSON.stringify(bundleInfo));
      let token = bundleInfo.appInfo.accessTokenId;
      tokenId = token.toString();
      if (usbManager.addDeviceAccessRight(tokenId, devicesName)) {
        console.log(`Succeed in adding right`);
      }
    }).catch((err : BusinessError) => {
      console.error('testTag getBundleInfoForSelf failed' );
    });
  } catch (err) {
    console.error('testTag failed');
  }

Before change: When the system application calls a system API, if the ohos.permission.MANAGE_USB_CONFIG permission is not configured in the permission field in the configuration file, error code 202 is returned.

After change: When the system application calls a system API, if the ohos.permission.MANAGE_USB_CONFIG permission is not configured in the permission field in the configuration file, error code 201 is returned.
