I connect two USB devices to my Android 3.1 tabled and I try to iterate over all of them and request the permission for each:

UsbManager mManager = (UsbManager) context.getSystemService(Context.USB_SERVICE);
...
for (UsbDevice device :  mManager.getDeviceList().values()) {
  mManager.requestPermission(device, mPermissionIntent);
  ...           
}

The issue is that only one permission screen appears instead of two and I suspect requestPermission causing this. Are there any workarounds in Android for that?

    My workaround is, if there are multiple permission requests to be issued, issue one at a time. That is, after the receiver has got the response to the first permission request, issue the next request. I tested this workaround last night, and it solved the missing permission screen and missing response problem. I am using Android 4.x.
