usb Splitter

[mrmagicm]

I have a usb splitter, just a standard one.....I discovered that with it, I cannot Connect an USB Key and A gamepad connected to my andoid TV.
The Two peripheral work when connected on the Tv's Android port.
Could someone explain to me why I cannot both peripheral at the same time??
Do I need a "special" splitter for android??

Probably draw too much amp that the usb hub can't handle when both device is connected to it.

This is what I tought, but I've changed my alimentation, A 12V 1,5A for an 12V 2A, the peripheral are a gamepad and a usbkey, do they drain that much?? Don't think so I don't think it's that, but it could be....Would anyone know something about that??
(I have ordered a 12V 3A to see if it changes anything) It's for an android box.

So for example if a usb port that only supply 5V and 1A, and plug in usb hub and two devices that draw 1A each they would disconnect, you still have to look at how much amp the the port can supply, in your case you might need a power usb hub.

I doubt it's that, because the android tv box is this: https://www.h96tvbox.com//product/h96max-v58/
It's quite recent..... Could it be that the 2 usb port a so bad to give a minimal power to peripheral??

They are probably 5V/0.5A, that what most usb port on these box are, that 12V/1.5A is the power supply.

What do you mean with "USB splitter"? Also yea, a gamepad could draw too much.

Hello communauty, as usual, it had nothing to do with what others said to me.
The solution: Even if your splitter works on pc, it might not work on both side of the slitter from usb, you have to have a SPECIFIC "OTG" splitter, when OTG is specifically mentionned, it will work fine on android.
Seems nobody knew this......
