OpenWrtにRTL8812AUドライバが追加されていたので試しに。ただ、以前と変わらず不安定な印象。
WI-U3-866D固有の問題である可能性も無きにしも非ず。
接続
普通にUSB 3.0ポートへ接続。何故かUSB 2.0デバイスとして認識され、そのままUSB 3.0接続への切り替え等は発生しない。
iwinfo ではwlan2がWI-U3-866Dに該当。

AP接続試行時
LuCI上からスキャン / 接続操作。何故か uninit が走る。この時点で
iwinfo や iw dev の情報からドングルが消える。

ドングル取り外し
上のスキャン / 接続操作の後ドングルをUSB 3.0ポートから引き抜く。Oopsを吐いた後、そのままKernel Panicを起こしてお亡くなりになり、reboot。
