Last week I bought a usb 3.0 hub from tplink which offers 3 usb 3 ports and a gigabit internet port. I connected the hub to my Asus Zenbook 14 UM3402YAR laptop. After I wanted to test if the wired internet connection works, I ran an internet speed test and the first time in Ubuntu the connection simply dropped shortly after it went up to maximum downlink. I moved to Windows because I have a dual boot system to see if there does the same and the fact does it worked. Afterwards I wanted to transfer some files to my computer from a USB stick, and it read the USB stick very slowly and the HUB driver that comes with Windows failed. The data on the USB stick is safe. I could tell something was really wrong. I tried the hub to see if it's faulty using another computer and it works on two other machines without error. I did on the current Asus Zenbook laptop a file transfer test without the hub and it works without problems. I figured out that it's a problem with the laptop's usb port not knowing how to handle the hub properly. I tried the following:
- uninstalled and reinstalled generic drivers
- installed the drivers from the vendor
- changing power settings to balanced or high power to see if it is a problem from the power save mode
- disabling power save on the all usb drivers
I can't really find a solution on this. I read something about a setting called Disable Selective Suspend in the power plan settings > change advanced power settings, but there is no setting for me to change in that way. Also I only have the balanced power plan there. Any ideas how can I make my usb hub working? thanks for your attention
