How to add ComFast's CF-811AC Usb adapter driver

Hi, everyone!
I have a Usb wifi adapter ComFast CF-811AC, its chip is about RTL8811CU, and I have searched openwrt's firmwares, and find nothing. Now CF-811AC is still not working.
Can anyone help me out!

Be aware that USB wireless devices aren't exactly up to 24/7 operations or AP mode anyways, aside from Realtek specific issues.

Thank you! Realtek maybe want to earn more new money but lost its old customs. I will not buy its products.
By the way, how about a MW150US usb adapter with Ralink MT7601 chip, or a usb adapter with RT3070/RT3070L chip? Would you like to give some suggestions? Thanks a lot.
