Not working via powered USB hub connected to VitaTV #9

The plugin doesn’t mount the USB stick when it is connected to a powered USB hub instead of directly to the VitaTV.

I mean that sucks but there's like nothing I can go on here.

I should have elaborated more. Here are some details:

On the other hand

Therefore the problem is not he stick or the hub, but something during the mounting at boot that causes it to fail. Maybe not enough time allowed during boot to detect hub+stick? I am using the latest version of boot the plugin.

Edit: hmm it works every once in a while. I just rebooted a few times and one time it mounted correctly. Out of 20 boots it mounted correctly only once. Maybe it is a slow stick and needs one more second or so to allow enough time for hub plus stick to be recognized.

By itself the stick always mounts correctly at boot time. But when connected to the hub it only works every once in a while. The hub is a regular powered Amazonbasics usb 3 hub with 4 ports.

I found out something else: Everything works perfectly if I don’t power the hub but let it be powered by the Vita.

So somehow the problem is related to whether the hub is powered or not. I wonder if the method used to detect the stick during boot time relies on turning the power to it off and back on? This would explain why it doesn’t work when there’s external power to the hub.

It was the hub. I bought a second, different hub. The new one is an Amazonbasics 10 port USB 2.0 powered hub. It works perfectly.

The one that shows problems is the Amazonbasics 4 port powered USB 3.0 hub.

Since it is a problem with only one particular powered hub, I will close the issue.
