[Solved] Asus AC56 usb wireless not detected

Hello,

Today I've bought an Asus AC56 usb wireless adapter and installed it's firmware by downloading the appropriate chipset driver
of the device from aur (url: https://aur.archlinux.org/packages/rtl8 … mments=all). But I've noticed that
the device is not listed in lspci by viewing the output and storing the output of the command to a file when the device is
plugged or unplugged using the following commands:

lspci -k > x # when the wireless is unplugged
lspci -k > y # when it's plugged
diff x y # returns no output

The output of ip link lists all the old adapters already installed.

I've got an Asus PCE AC-88 PCI-E wireless card installed and working on Arch 4.14-6 using a reverse engineered driver.
Does this card interfere with the new card and why is the device not listed?

Your lspci is not going to change for an USB device. That's lsusb's job.

Alright, I've used the wrong command, but why doesn't it show the interface of the wireless card even though I've installed the drivers?
Do I need to enter a command to activate that wireless card?

I've managed to get my wireless interface running. I hade to install the linux headers and update the system with
pacman -Syu.
