Hello ,
I want to build a USB splitter
so I will be able to connect 2 usb devices to my computer
something like 2 USB camera for example

I have try to connect all the cables together but it will only show me 1 usb device

how do i do this?

Thanks ,

 

You need to provide a USB end point and start point,
which is a chip .

qed, you need a hub.

don't mind using a chip
i jusr want to build a circuit of hub on my own
so I can put it in my own IC

Thanks

 

Ar you using two usb devices at the same time?
If they are not using at the same time then you can use the switches to built it.
A lot of usb hubs in the market, why you want to build your own?

 

I need to build a IC board
and I need to connect it to a computer with only 1 USB port
and in my board I have 2 usb device that need to be connected

 

The usb hubs already have the function to match what you need, why you insist to build your own?

I need \ want it to be on my circuit as
I dont want to add external device
so in the end i will have a circuit that know how to do it
can't be that hard....
