Device is not reaching the transmit/receive mode

Hello everyone. I have a trek1000 evaluation kit with 4 evaluation boards (EVB1000). Unfortunately, a device cannot reach a transmit/receive mode (i.e. LED3 and LED4 are off). This functionally depends on the firmware. As a result, I cannot identify this device with the USB cable in my lapton and therefore cannot use it during the experimental test. A possible solution is, maybe?, to reload the firmware on this device. If this solution is possible, how can I do it? However, if there is another (better) solution can I have some suggestions to solve my problem?

Thanks in advance for your support.
