Hi Tim,
I was able to install the driver:
$ lsmod | grep 8192 8192eu 1544192 0 cfg80211 851968 1 8192eu vmw_vmci 81920 0
The forum thread you reference is from 2016 and says
Something interesting, support for this device will be in the 4.9 kernel using the rtl8xxxu driver, then you won't need any external drivers anymore
What I did was installing the this[1] aur package, then manually insert the module into the kernel. [1]https://aur.archlinux.org/packages/rtl8192eu/
But if you read that whole thread, https://bbs.archlinux.org/viewtopic.php?id=218152, it says rtl8xxxu will soon be the driver to use, not 8192eu. The first post in it also gives a USB ID of 2357:0109 for the device but I can't find the Wi-Fi device in your output of ‘lsusb’. Which one is it?
