Usb Peer To Peer

[locus]

Is it possible to create a peer to peer connection between two PC's via their usb ports using a simple plug 'A' to plug 'A' usb cable.

I am trying to transfer data serially between the two PC's.

Any suggestions on how to do this is welcomed.

Thank you very much for your attention.

For peer-to-peer connection you need a special cable with additional wire and A/B connectors that won't fit to standard 'A' receptacle. Also the USB host on the PC must be able to recognise such cable and switch either to master (host) or slave (device) mode. The USB OTG supplement was meant for portable devices, so I doubt that your PC will support it.

There might be some hardware bridges that will allow you to do this, for example USB <-> COM converters or similar.
