Volumio Sparky 2.586 USBridge - MAC Address Rewritten

Volumio Sparky 2.586: The OS is changing the MAC addresses of my two Allo USBridge devices to … the same address. Why? Please fix, and please instruct me in how to rectify in the short-term.

Thanks

To be clear: each sparky device is reporting the same MAC address: 00:17:f7:01:00:01. The manufacturer component appears to be correct. The last three components are not.

I have the same issue. How did you resolve this?
