USB WiFi Dongle (TL-WN725N) not detected after reboot on AML-S905X-CC

Hi everyone,

I’m experiencing an issue with my Le Potato (AML-S905X-CC) regarding a TP-Link TL-WN725N WiFi dongle.

The Problem: Every time I reboot the system, the WiFi dongle stops working. It is not recognized by the OS until I physically unplug it and plug it into a different USB port. Once swapped, it connects automatically and works perfectly until the next reboot.

Setup Details:

  • Board: AML-S905X-CC (Le Potato)

  • WiFi Dongle: TP-Link TL-WN725N (Realtek RTL8188EUS chipset)

  • OS: Ubuntu server → ubuntu-22.04.3-preinstalled-server-arm64+aml-s905x-cc.img

I’ve tried different USB ports, but the behavior is consistent: it requires a physical “re-plug” or port swap to initialize after a warm boot.

Is there a known fix for USB power cycling or a driver parameter I should adjust to ensure the dongle initializes correctly on boot?

Thanks in advance!
