From bf1103654df99d50724a022c8b9fca8908a86f50 Mon Sep 17 00:00:00 2001 From: Bitterblue Smith Date: Wed, 2 Apr 2025 18:30:02 +0300 Subject: [PATCH] wifi: rtw88: usb: Enable switching the RTL8814AU to USB 3 The Realtek wifi 5 devices which support USB 3 are weird: when first plugged in, they pretend to be USB 2. The driver needs to send some commands to the device, which make it disappear and come back as a USB 3 device. The method used to switch the RTL8812AU also works for the RTL8814AU.
