Review of Linux Compatibility

The Rosewill AC1200UBE is a USB WiFi adapter with USB ID 0bda:0812

Bus 001 Device 004: ID 0bda:8812 Realtek Semiconductor Corp.

The stick supports WiFi connections according to IEEE 802.11ac standard an bases on the Realtek RTL8812AU chipset. This chipset is supported by the kernel driver “8812au” since Linux kernel version 3.18.5.
If such a kernel version is used the stick is automatically recognized and fully supported by the Linux kernel:

usb 1-1.1: new high-speed USB device number 3 using ehci-pci
usb 1-1.1: New USB device found, idVendor=0bda, idProduct=0811
usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.1: Product: 802.11ac WLAN Adapter
usb 1-1.1: Manufacturer: Realtek
usb 1-1.1: SerialNumber: 00e04xxxxxx

The driver can be downloaded from kernels < 4.0 from

wget https://github.com/gnab/rtl8812au/archive/master.zip

and for kernel 4.0.0 compatible version from

https://github.com/csssuf/rtl8812au/archive/master.zip (kernel 4.0.0 compatible pull)

Afterwards, the file needs to be unzipped:

unzip master.zip
cd rtl8812au-master

Power saving should be disabled for this stick, i.e. edit the file rtl8812au-master/Makefile and replace CONFIG_POWER_SAVING = y with CONFIG_POWER_SAVING = n .
Afterwards, compile and install the kernel module:

make
insmod 8812au.ko
mkdir /lib64/modules/$(uname -r)/kernel/drivers/net/wireless/rtlwifi/rtl8812au
cp 8812au.ko /lib64/modules/$(uname -r)/kernel/drivers/net/wireless/rtlwifi/rtl8812au
depmod -a

The driver should be loaded after the next reboot.
