<![CDATA[Starling 2 Max: WiFi dongle USB link (error -71,) - dongle tested good on PC]]>Hardware: Starling 2 Max, SKU MRB-D0012-4-V2-C29-T9-M22-X0 (V2, T-Motor)

Software: voxl-suite 1.3.5, system image 1.7.10-M0054-14.1a-perf

Stock RTL8821CU WIFI dongle keeps dropping off the USB bus: "device descriptor read/64, error -71", "device not accepting address", and "usb usb1-port1: Cannot enable.

Fails with the aircraft untouched. Battery power-cycle revives it temporarily.

Same day, I tested this same dongle on a Windows PC: clean enumeration, 0% loss ping. Fine on PC, dies in 12 s on the drone

Is this a known issue?
