Is it possible to restore more a device while another one is being usb-connected?

[ICE-FlatLine]

I have 2 devices, connected to the same Mac. I am trying to restore one of them and getting this error after device enters recovery mode:

However, when only one device is connected, restore works. Is there a limitation for one iOS device connected?

Yes. It's possible to support this but currently isn't supported. During the update we reconnect to the device several times and probably in at least one of them the reconnection occurred to the other one

Thanks.
