Realtek RTL8192EU Wireless 802.11n 2x2 USB 2.0

I have the above wifi dongle plug in, during bootup, openwrt detected: 0bda:818b, which is correct for RTL8192EU.

then I install the driver... and the dongle is not found in Openwrt Wireless

what can I do? I missed out something?

"The driver" -- which one? suggests that the rtl8xxxu driver is needed. -- the package description and its warnings should be read

linux$ fgrep -r 818b drivers/
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:		case 0x818b:
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:{USB_DEVICE_AND_INTERFACE_INFO(USB_VENDOR_ID_REALTEK, 0x818b, 0xff, 0xff, 0xff),
