Hi, I happen to own a RTL8192EU WiFi dongle which is marked as untested
by the rtl8xxxu driver.

I'm on a linux from scratch system using kernel 4.7.3 and wpa_supplicant
2.5.

The dongle appears to connect and work fine, but after around 10 minutes
it deauthenticates and enters and endless loop of authentication
timeout. This continues even if I bring the interface down and back up
again. The only way to restore the connection is to physically remove
and re-plug the usb dongle.

I have attached a dmesg log of connecting and entering the auth loop.
