I have just purchased an ASUS USB-AC53 USB WLAN adapter.

This adapter identifies itself as follows:

ugen0.2: <Realtek 802.11ac NIC> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) 
pwr=ON (500mA)

   bLength = 0x0012
   bDescriptorType = 0x0001
   bcdUSB = 0x0210
   bDeviceClass = 0x0000  <Probed by interface class>
   bDeviceSubClass = 0x0000
   bDeviceProtocol = 0x0000
   bMaxPacketSize0 = 0x0040
   idVendor = 0x0b05
   idProduct = 0x184c
   bcdDevice = 0x0210
   iManufacturer = 0x0001  <Realtek>
   iProduct = 0x0002  <802.11ac NIC>
   iSerialNumber = 0x0003  <123456>
   bNumConfigurations = 0x0001

There's a match for this driver in /usr/src/sys/contrib/dev/rtw88/rtw8822bu.c:

         { USB_DEVICE_AND_INTERFACE_INFO(0x0b05, 0x184c, 0xff, 0xff, 0xff),
           .driver_info = (kernel_ulong_t)&(rtw8822b_hw_spec) }, /* ASUS U2 */

but if I load rtw88, nothing happens.

Is there any step I'm missing to make this adapter work?

Yours,
Robert Clausecker

I  have never used this adapter, but do you have net/wifi-firmware-rtw88-kmod installed?
