Message-Id: <20240625070724.22044-1-tuhaowen@uniontech.com> Date: Tue, 25 Jun 2024 15:07:24 +0800 From: tuhaowen <tuhaowen@...ontech.com> To: stern@...land.harvard.edu, gregkh@...uxfoundation.org Cc: linux-usb@...r.kernel.org, usb-storage@...ts.one-eyed-alien.net, linux-kernel@...r.kernel.org, wangyuli@...ontech.com, tuhaowen <tuhaowen@...ontech.com> Subject: [PATCH] drv/usb: Fix the issue with Realtek USB wireless adapter AC650 Due to the dual-mode functionality of the Realtek USB wireless adapter AC650, it initially presents itself as a flash drive before the driver is installed. In Linux, multi-state devices are recognized as storage devices on startup because the driver has not yet been loaded. As a result, the AC650 is identified as a DISK device at boot, preventing the use of its WLAN mode. The issue can only be resolved by unplugging and replugging the adapter.
