Warum funktioniert meine erzwungene MAC-Adressenänderung nicht (Raspberry Pi)?

Ich arbeite mit Raspberry Pi Zeros in einem Subnetz. Ich habe jeweils externe Ethernet-Adapter gekauft, um sie miteinander zu verbinden. Leider hatten diese Ethernet-Adapter alle die gleichen MAC-Adressen, was die Kommunikation zwischen den Pis nahezu unmöglich machte.

Aus diesem Grund habe ich versucht, eine Änderung der MAC-Adressen zu erzwingen, indem ich sie /etc/systemd/network/00-default.linkin jedem Pi-Nullpunkt entsprechend den in diesem Beitrag beschriebenen Schritten editiere . Letztendlich habe ich folgenden Code verwendet:

[Match] MACAddress=00:e0:4c:53:44:58  [Link] MACAddress=10:00:00:00:00:11 

Beachten Sie, dass ich für jedes Pi eine andere neue MAC-Adresse verwendet habe

Leider wurde nach dem Neustart aller Pi-Nullen keine der MAC-Adressen auf die neuen zugewiesenen Werte aktualisiert. Wenn ich mit ifconfigihnen nachsehe, waren alle die gleichen ursprünglichen Werte geblieben. Was mache ich falsch?

Zusätzliche Information:

ip neighbor show ergibt folgendes Ergebnis:

pi@raspberrypi:~ $ ip neighbor show 192.168.2.37 dev wlan0 lladdr ac:bc:32:87:93:39 DELAY 192.168.3.12 dev enxb827eb9c0ecf lladdr 00:e0:4c:53:44:58 STALE 192.168.3.10 dev enxb827eb9c0ecf lladdr 00:e0:4c:53:44:58 STALE 192.168.3.11 dev enxb827eb9c0ecf lladdr 00:e0:4c:53:44:58 STALE 192.168.2.1 dev wlan0 lladdr 40:c7:29:4e:4d:f8 STALE 

ifconfig zeigt an:

Ich habe auch eine statische IP in /etc/dhcpcd.confso gesetzt:

interface eth0 static ip_address=192.168.3.12 

lsusb ergibt die Ausgabe:

dmesg ergibt die Ausgabe:
