Hi,
The Mercusys MA60XNB (AX900 Nano USB WiFi 6 adapter) works with the rtw89_8851bu driver but its USB ID (2c4e:0128) is not in the device table. Windows identifies the chipset as RTL8851BU.
Adding the following entry to rtw_8851bu_id_table in rtw8851bu.c makes the adapter fully functional:
{ USB_DEVICE_AND_INTERFACE_INFO(0x2C4E, 0x0128, 0xff, 0xff, 0xff), .driver_info = (kernel_ulong_t)&rtw89_8851bu_info },
Tested on Fedora 44 with kernel 7.0.8-200.fc44.x86_64 and linux-firmware 20260410-1.fc44.
USB device details:
idVendor 0x2c4e Mercucys INC
idProduct 0x0128
iProduct 2 802.11ax WLAN Adapter
iManufacturer 1 Realtek
bcdUSB 2.00
bNumInterfaces 3
Thanks,
Guillem

I made a format patch [1] by this ID. Please check if it is expected.

Hi,
Yes, that's correct. The adapter works with this ID after compiling and
probing your patch.
