two USB slave:Interface

I want to transfer data stream from one USB slave chip to another USB slave chip(single direction). Shall I interface a hub chip between them? Or can I interface them without a hub chip? May you please recommend some references?

Any suggestions will be appreciated!

Best regards, Davy

Won't work.

USB is a strictly host-centric protocol. One consequence of that is that devices never talk to each other --- all communication *must* be with the host (optionally through a couple layers of hubs). Unless those USB devices are actually on-the-go" devices (quite rare things, those), what you want to do is impossible.

Hi,

Thank you all for your help?

I have two more problem:

For the "host" scheme, shall I have two chip one hub chip and one master chip to do the transfer?

For the "USB OTG" scheme, is the OTG a matured technology and is there any producer provide the OTG chip?

Best regards, Davy
