I have two routers, both Archer BE230 models, connected via EasyMesh. The first router is set as the main router, and the second is set as the satellite router. Both routers can manage USB storage through their Web UI.

The main router can recognize USB storage normally when inserted. However, the satellite router cannot recognize USB storage when inserted (I used the same USB storage for testing on both the main router and the satellite router, so the USB storage itself is definitely not the issue).

Could this be a bug in the router when configured as a satellite router?

The figure below shows the USB storage through the Web UI on the satellite router.
