We have also faced another problem in the XLink component, during our work.
When we are trying to reset the stalled device, first we send the USB_PING_REQ command. But, if we had any problems recently, we may receive the command USB_READ_REL_REQ from Movidius. And that is the situation, cause the origin XLink component does not expect any other answer except USB_PING_RESP. So, in this case, XLink component hangs waiting for an answer that it will never receive.
Maybe this problem is only specific for the source code of APIv1 and APIv2, but we also received similar errors, using the OpeVino.
Please, check this situation.
