Problem running on CentOS 8 #113

I'm trying to get my Wifi adapter to work under CentOS 8.3 (kernel 4.18.0-240). I copied this repository onto the machine, installed dkms, and successfully installed the module. But when I connect the USB Wifi adapter or reboot the computer, it still fails to recognize the adapter. It shows up in lsusb as 0bda:c811, which is supposed to be supported by this module, right? This is the output I get from dmesg during booting:
