I will really like to hear what the root cause of this is. This makes me think of the bug that the QCA AR9331 SoC has. The AR9331 is extremely common in small travel routers, but it has a fun bug where one of it's clock sources is shared between the 802.11 wifi and the USB port. IF the USB port is negotiated at USB 1.x speeds AND the 802.11 radio is scanning, the USB will freak out and die. This generally requires the 802.11 radio to be in client mode rather than AP mode. You can read some details about this on the old OpenWRT forum, if it survived the great forum purge of 2018.
