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.
