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?

Hi @electroaj
It's intermittent but it's gotten worse over about three weeks. Dongle would vanished from the USB bus mid-session. And then at boot the dongle enumerated for under a second, then went into the device descriptor read/64, error -71 . No software path recovered adb reboot didn't help. Only a physical restart (unplugging and plugging back to power), would bring back now even that has been inconsistent. Sometimes it would last 30 minutes after physical restart sometimes just a few seconds.
